Dog Seizures: What to Do, and What Treatment Costs
A burst of abnormal electrical activity in the brain, which in its classic form drops the dog on its side with stiff, paddling limbs, frothing, loss of consciousness and often loss of bladder and bowel control. This is an emergency and needs a vet now if any of these are true: A seizure that has lasted more than five minutes, or is still going; More than one seizure in a 24-hour period (cluster seizures).
Is this an emergency?
Worst first. Find the highest rung that matches what you can actually see, and act on that one — not on the one you hope applies.
- Emergency — go nowGo to an emergency vet or the nearest open clinic now. Do not wait for morning.
- A seizure that has lasted more than five minutes, or is still going
- More than one seizure in a 24-hour period (cluster seizures)
- The dog does not fully come round between seizures
- The dog is hot to the touch after a long seizure, or is struggling to breathe
- A first seizure in a dog with known access to a toxin, or in a dog that is also vomiting, staggering or collapsed
Cornell is unambiguous: an active seizure lasting more than five minutes (status epilepticus) or multiple seizures in a 24-hour period is a medical emergency, all status epilepticus is life-threatening and some cluster seizures are too, and the dog should be taken to the nearest emergency veterinarian immediately. Merck describes the same endpoint — poor seizure control leading to clusters, status epilepticus and death. Treatment is intravenous benzodiazepine to break the seizure. Cornell's practical addition: if the seizure resolves on the way in and the dog stays quiet, the life-threatening emergency is over and the dog still needs to be seen, but not necessarily at an emergency fee.
- Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
- A first-ever seizure in a dog of any age, once it has stopped and the dog is quiet
- A first seizure in a dog under one year old, or over six years old
- Seizures that are becoming longer, more frequent or more violent
- Blindness, circling or severe disorientation persisting for hours after a seizure
- A known epileptic having breakthrough seizures on medication
Cornell: after a first seizure, stay calm, stay safe, time it, and schedule a veterinary examination as soon as possible — and get a video if you can, because the veterinarian's first job is to decide whether this was a seizure at all. Age brackets the differential: Cornell notes dogs under a year are more likely to have a congenital defect, an intoxication or an infectious disease such as distemper, and dogs over six at their first seizure are more likely to have a metabolic disorder or a structural lesion such as a tumour or a stroke. Cornell also lists post-ictal blindness lasting up to three days as one of the exceptions that justifies starting medication after a single event.
- Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
- Isolated, brief focal events — repeated eyelid, lip or ear twitching, 'fly biting', a 'chewing gum' jaw clack
- A stable, well-controlled epileptic due routine blood work
- A dog with a first seizure more than six months ago and none since
- Reviewing a seizure log to decide whether to start medication
Cornell: focal seizures usually do not require treatment, but a focal seizure can segue into a generalised one, so keep watching until it passes. This is also the rung where the treat-or-wait decision gets made, and Cornell explains it honestly — a dog may never have another seizure, once an antiepileptic is started it is generally for life, and there is a real cost in both drug burden and money to treating a dog that does not need it. Their thresholds: antiepileptic drugs are generally recommended for more than two seizures in six months, and Dr Early's rule of thumb is to start if there is more than one seizure a month. Blood work at intervals is not optional once medication starts, because levels have to be kept in the therapeutic range.
- Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
- An at-risk breed with no signs — Cornell names Beagles, Bernese Mountain Dogs, Border Collies, Boxers, Cocker Spaniels, Labrador Retrievers and Golden Retrievers
- A dog whose seizures are controlled, being logged at home
- Keeping video and a written record of date, duration, appearance and post-ictal behaviour
The seizure log is the monitoring, and Cornell treats it as clinical data: record when the seizure happened, what it looked like, how long it lasted and how the dog behaved before and afterwards, and video it if possible. That record is what decides whether medication starts, whether a dose changes, and whether apparent breakthrough seizures are drug tolerance. Merck adds a finding worth knowing: a study found seizure-precipitating factors present in approximately 74% of seizure cases, most frequently stress, sleep deprivation, weather changes and hormonal fluctuations.

If a seizure is happening now, the number that matters is five minutes. Cornell's Dr Peter Early defines status epilepticus as an ongoing seizure that does not self-resolve, typically past five minutes, and it is life-threatening because the physical activity drives core body temperature to fatal levels.
What to do while it is happening
Nothing to the dog, and several things to the room. Cornell's instructions are to clear breakable or falling objects away, to stay below the dog on stairs if you can do so safely, and to keep away from the mouth — a dog is not aware of its surroundings during a seizure and may be disoriented or aggressive for minutes to hours afterwards.
Time it. A seizure feels far longer than it is, and the difference between three minutes and six minutes is the difference between an appointment and an emergency drive. Two or more seizures in a 24-hour period is also emergency territory, and so is a dog that does not fully come round in between.
Cornell adds a practical note that saves money without costing safety: if the seizure resolves on the way in and the dog stays quiet, the life-threatening emergency is over. The dog still needs to be seen — not necessarily at an emergency fee.
How common is epilepsy in dogs, really?
Merck's summary of published studies gives 0.5% to 0.82% in nonreferral populations and 1% to 2.6% in referral hospital settings.
Those two are not the same measurement and should not be averaged. The referral figure is inflated by the fact that dogs with seizures are exactly the dogs who get referred; the nonreferral range is the one that approximates an ordinary dog's risk. It is also a range across studies rather than a single counted cohort, which is a weaker warrant than a primary-care prevalence.
When does medication actually start?
Here our sources disagree, and we are publishing all three rather than picking one. Cornell's written guidance is that antiepileptic drugs are generally recommended for more than two seizures in six months. Cornell's Dr Early gives a rule of thumb of more than one seizure a month. Merck says medication is often started after the second or third documented seizure, typically more than two in a six-month period.
The reason the threshold exists at all is that starting is close to permanent. Cornell's framing is honest about both sides: a dog may never have another seizure, once an antiepileptic is started it is generally for life, and there is a real cost in both drug burden and money to treating a dog that does not need it.
There are exceptions that justify starting after a single event, and Cornell names one of them — post-ictal blindness lasting up to three days.
The seizure log is the diagnostic test
Cornell treats it as clinical data rather than as a diary: record when the seizure happened, what it looked like, how long it lasted, and how the dog behaved before and afterwards. Video it if you can.
That record decides whether medication starts, whether a dose changes, and whether apparent breakthrough seizures are drug tolerance rather than disease progression. It costs nothing and it is the single highest-value thing an owner does.
It also finds triggers. Merck reports a study in which seizure-precipitating factors were present in approximately 74% of seizure cases, most frequently stress, sleep deprivation, weather changes and hormonal fluctuations. Several of those are manageable once they have been noticed.
Was it actually a seizure?
The vet's first job, and the reason the video matters. Dr Early names the two events most often mistaken for one: a vestibular episode, which shows loss of balance, incoordination, head tilt and nystagmus, and an intermittent cardiac arrhythmia, where the collapse is softer, more like fainting, with a quicker recovery.
Focal seizures are the other confusion, running the other way. Repeated eyelid, lip or ear twitching, "fly biting", a chewing-gum jaw clack — Cornell says focal seizures usually do not require treatment, but that one can segue into a generalised seizure, so they are watched rather than ignored.
How age changes the work-up
Cornell brackets it. A dog under one year at its first seizure is more likely to have a congenital defect, an intoxication, or an infectious disease such as distemper. A dog over six is more likely to have a metabolic disorder or a structural lesion — a tumour or a stroke.
Idiopathic epilepsy sits between them: Cornell puts typical onset at six months to six years with a median of 2.5 years, and it is a diagnosis of exclusion. That is why the blood work comes before the MRI, and why Cornell allows a presumptive diagnosis where referral imaging is limited, provided blood work and the neurological examination outside the post-ictal period are normal.
What happens if the medication does not work?
It happens often enough to plan for. Merck puts drug resistance at approximately one third of idiopathic epilepsy patients; Cornell's Dr Early puts the proportion needing more than one antiepileptic medication at approximately 20%.
There is also a failure mode that looks like disease progression and is not: Cornell describes some dogs developing tolerance as the liver metabolises the drug faster, so doses climb and side effects climb with them. That is what therapeutic drug monitoring is for, and it is a recurring appointment rather than a one-off.
Cornell names where the road can end in refractory cases, and we are not going to leave it out: where seizures remain frequent, severe and uncontrollable despite treatment, quality-of-life concerns may lead to consideration of humane euthanasia. Both refractory figures above are worth knowing before the first prescription rather than after the fifth.
What can be kept at home
Cornell describes rescue medication that an owner can be given for use during a seizure: diazepam dispensed for rectal administration, or intranasal midazolam. For dogs prone to clusters, Cornell describes keeping levetiracetam on hand so a few doses can be given after a seizure to head off the cluster.
All of those are prescribed for a specific dog, with a specific plan attached, and none of them is a reason to stay home. They shorten and lessen a seizure; they do not replace the assessment.
Merck's hospital equivalent is an intravenous benzodiazepine to break the seizure, with injectable levetiracetam an option for status epilepticus or clusters, and it points practitioners to the 2024 ACVIM consensus statement for the full algorithm.
What this costs over a dog's life
The emergency is the cheapest part and the least frequent. An emergency assessment is $85–$150 with $124 typical, and that is what breaking a cluster or a status epilepticus episode starts with.
The diagnosis is where the one-off spend sits. Blood work and urinalysis rule out the reactive causes, and where an extracranial cause is suspected — a portosystemic liver shunt, an insulin-secreting tumour — abdominal ultrasound is $383–$880 with $483 typical. MRI and cerebrospinal fluid analysis are referral-hospital procedures we do not yet price, and they are usually quoted together because they happen under one anaesthetic.
The real cost is the recurring one. Lifelong medication plus the monitoring appointments at $56–$130 each, several times a year, for as long as the dog lives — that is the number to think about at the moment the threshold is crossed, not the emergency fee. And euthanasia, at $110–$750, is on the list below because Cornell names it as an outcome of refractory epilepsy, and a page that describes lifelong medication without acknowledging where that road can end would not be telling you the truth.
Why seizures and epilepsy in dogs happens
- Idiopathic epilepsy
- The commonest cause, and a diagnosis of exclusion. Cornell: recurrent seizures with no identifiable underlying cause, typically starting between six months and six years of age with a median onset of 2.5 years. A genetic component is known in some breeds and suspected in others, epilepsy is more common in purebred dogs, and males may be more predisposed than females.
- Reactive seizures from metabolic disease
- Cornell: low blood sugar, low blood calcium, liver disease, liver shunts and kidney disease all cause seizures in a structurally normal brain. The defining feature is that correcting the metabolic problem makes the seizures go away — which is why the blood work comes before the MRI.
- Toxins
- Cornell names dark chocolate, caffeine, the sugar substitute xylitol, antifreeze, rat poison and liquor. Eliminating the exposure and treating the toxin resolves these seizures. This is the differential that changes the first question at the emergency clinic from 'how long did it last' to 'what could the dog have got at'.
- Structural brain disease
- Cornell: tumours, head trauma, inflammatory disease and infectious disease including rabies and canine distemper. Cornell puts dogs over six at their first seizure into this bracket alongside metabolic disease, which is why a middle-aged dog's first seizure gets a different work-up from a two-year-old's.
- Drugs that lower the seizure threshold
- Cornell lists this as a distinct cause of reactive seizures, resolved by discontinuing the drug. It is the reason the medication list is part of the history rather than an afterthought.
How a vet diagnoses seizures and epilepsy in dogs
Not every test below is run on every animal. Which ones are depends on what the examination finds, and each one is priced in the cost section further down.
- Neurological examination and history, with video
- Cornell: the veterinarian must first determine whether the event was actually a seizure, and a video is immensely helpful. Dr Early names the two things most often mistaken for one — vestibular events, which show loss of balance, incoordination, head tilt and nystagmus, and intermittent cardiac arrhythmia, where collapse tends to be softer, more like fainting, with a quicker recovery. What it costs
- Blood work and urinalysis
- Cornell: complete blood count, biochemistry and urinalysis to assess overall health and rule out systemic illness. This is the step that finds the low blood sugar, the liver shunt and the kidney disease, and it is the step that has to be normal before the word idiopathic can be used.
- MRI of the brain
- Cornell: the imaging best suited to rule out structural problems such as inflammation or a tumour. Not every dog needs it — Cornell allows that where referral imaging is limited, a presumptive diagnosis of idiopathic epilepsy can be made when blood work and the neurological examination (once past the post-ictal period) are normal and there are no other signs of illness.
- Cerebrospinal fluid analysis
- Cornell: CSF is analysed for pathogens and for elevated cell counts indicating inflammation or cancer. Usually done under the same anaesthetic as the MRI, which is part of why the two are quoted together.
- Abdominal ultrasound where an extracranial cause is suspected
- For the reactive-seizure branch. A portosystemic liver shunt or an insulin-secreting pancreatic tumour causes seizures in a brain that will image normally, and neither is found by a neurological examination. What it costs
How seizures and epilepsy in dogs is treated
- Emergency treatment of status epilepticus or clusters
- Cornell: emergency veterinary intervention with intravenous medication, usually a benzodiazepine such as diazepam, to break the seizure. Merck notes that levetiracetam by injection at 30-60 mg/kg intravenously over 5-15 minutes may be used for status epilepticus or cluster seizures, and points practitioners to the 2024 ACVIM consensus statement on the management of status epilepticus and cluster seizures in dogs and cats for the full algorithm. What emergency treatment of status epilepticus or clusters costs
- Home rescue medication
- Cornell: diazepam can be dispensed for rectal administration during a seizure with a syringe and rubber tube, and often shortens and lessens the seizure; intranasal midazolam is another benzodiazepine that can be given at home. For dogs prone to clusters, Cornell describes keeping levetiracetam on hand so a few doses can be given after a seizure to head off the cluster.
- Long-term antiseizure medication
- Cornell's first choices are phenobarbital, levetiracetam (Keppra), zonisamide and potassium bromide, and notes zonisamide and levetiracetam have become popular because they work well with minimal side effects. Merck's first-line phenobarbital dose is 2-5 mg/kg orally every 12 hours. The practical catch Cornell raises with levetiracetam is dosing frequency — it is short-acting and needs three-times-daily dosing, with the extended-release form allowing twice daily. What long-term antiseizure medication costs
- Therapeutic drug monitoring
- Cornell: medication therapy requires regular veterinary appointments for blood work, because levels must be high enough to help without causing harm. Cornell also describes a specific failure mode — some dogs develop tolerance as the liver metabolises the drug faster, so doses climb and side effects climb with them.
- A medium-chain triglyceride diet
- Cornell: a therapeutic diet containing medium-chain triglycerides, which block one of the brain receptors responsible for seizures, is an option especially for refractory cases, and Cornell states studies have shown a significant reduction in seizure activity when epileptic dogs are fed it. Adjunctive, not a replacement for medication.
- Quality-of-life decisions in refractory epilepsy
- Cornell names it directly: in refractory cases where seizures remain frequent, severe and uncontrollable despite treatment, quality-of-life concerns may lead to consideration of humane euthanasia. Merck puts drug resistance at approximately one third of idiopathic epilepsy patients; Cornell's Dr Early puts refractory epilepsy needing more than one medication at approximately 20%. Both numbers are worth knowing before the first prescription rather than after the fifth. What quality-of-life decisions in refractory epilepsy costs
Outlook and prevention
Cornell: many dogs achieve good seizure control with antiepileptic drugs, but complete disappearance of all seizure activity is rare and lifelong medication is typically necessary once management starts. Merck puts drug resistance at approximately one third of idiopathic epilepsy patients; Cornell's Dr Peter Early gives approximately 20% requiring more than one antiepileptic medication. Some dogs develop tolerance over time as the liver metabolises the drug faster, forcing higher doses and stronger side effects. Merck notes that status epilepticus is a serious challenge and usually carries a guarded to poor prognosis. Cornell also raises a question the literature has not settled: dogs show abnormal MRI lesions after a seizure — post-ictal changes thought to be a mix of cellular damage, stress and swelling — and while these reverse with time in humans, whether the same is true in dogs needs further study.
Idiopathic epilepsy cannot be prevented, but three things reduce the number of seizures a dog has. Remove the toxins on Cornell's list from reach — dark chocolate, caffeine, xylitol, antifreeze, rat poison and alcohol. Give medication on time, every time, because missed doses are a common cause of what looks like drug failure. And use the seizure log to find triggers: Merck reports a study finding seizure-precipitating factors present in approximately 74% of cases, most frequently stress, sleep deprivation, weather changes and hormonal fluctuations, several of which are manageable. During a seizure itself, Cornell's safety instructions are to clear breakable or falling objects away, stay below the dog on stairs if you can do so safely, and keep away from the mouth — a dog is not aware of its surroundings during a seizure and may be disoriented or aggressive for minutes to hours afterwards.

Not every line appears on every invoice — practices bundle differently, and some of these are only billed when the procedure turns up something. Sourcing for each figure is in Sources.
Does pet insurance cover seizures and epilepsy in dogs?
Dog Ultrasound is normally covered by a standard accident-and-illness policy. Diagnostic imaging ordered to investigate a covered illness or accident is reimbursable under a standard accident-and-illness policy - Embrace lists diagnostic testing for covered illnesses including biopsies, X-rays and MRIs, and carriers generally treat ultrasound the same way. The scan follows the condition: if the underlying problem turns out to be pre-existing or excluded, the imaging that diagnosed it is excluded too. A screening ultrasound with no clinical signs is preventive care and is not covered. No carrier we checked names ultrasound explicitly in its published coverage wording.
What you would get back: 70-90% of the covered bill after the annual deductible, following whatever treatment of the underlying condition is covered.
The catch, and it is the one that matters here: every US carrier excludes pre-existing conditions. If your animal has already been seen for seizures and epilepsy in dogs — or for signs a vet later links to it — a policy bought today will not pay for this episode. Cover is something you buy before the diagnosis, which is why the $56–$880 above is worth knowing while your pet is still well.
Waiting periods, and what each carrier counts as pre-existing, differ enough that the only useful answer is a side-by-side: our pet insurance comparison for dog ultrasound shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.
Common questions
Is seizures and epilepsy in dogs an emergency?
Treat it as an emergency if any of these are true: A seizure that has lasted more than five minutes, or is still going; More than one seizure in a 24-hour period (cluster seizures); The dog does not fully come round between seizures; The dog is hot to the touch after a long seizure, or is struggling to breathe; A first seizure in a dog with known access to a toxin, or in a dog that is also vomiting, staggering or collapsed. Cornell is unambiguous: an active seizure lasting more than five minutes (status epilepticus) or multiple seizures in a 24-hour period is a medical emergency, all status epilepticus is life-threatening and some cluster seizures are too, and the dog should be taken to the nearest emergency veterinarian immediately. Merck describes the same endpoint — poor seizure control leading to clusters, status epilepticus and death. Treatment is intravenous benzodiazepine to break the seizure. Cornell's practical addition: if the seizure resolves on the way in and the dog stays quiet, the life-threatening emergency is over and the dog still needs to be seen, but not necessarily at an emergency fee.
How much does it cost to treat seizures and epilepsy in dogs?
Costs for seizures and epilepsy in dogs run from $56 for routine vet checkup (wellness exam) to $880 for dog ultrasound. A severe case can run past the top of that range — what treatment adds depends on how bad it gets.
How is seizures and epilepsy in dogs diagnosed?
Neurological examination and history, with video: Cornell: the veterinarian must first determine whether the event was actually a seizure, and a video is immensely helpful. Dr Early names the two things most often mistaken for one — vestibular events, which show loss of balance, incoordination, head tilt and nystagmus, and intermittent cardiac arrhythmia, where collapse tends to be softer, more like fainting, with a quicker recovery. Blood work and urinalysis: Cornell: complete blood count, biochemistry and urinalysis to assess overall health and rule out systemic illness. This is the step that finds the low blood sugar, the liver shunt and the kidney disease, and it is the step that has to be normal before the word idiopathic can be used. MRI of the brain: Cornell: the imaging best suited to rule out structural problems such as inflammation or a tumour. Not every dog needs it — Cornell allows that where referral imaging is limited, a presumptive diagnosis of idiopathic epilepsy can be made when blood work and the neurological examination (once past the post-ictal period) are normal and there are no other signs of illness. Cerebrospinal fluid analysis: Cornell: CSF is analysed for pathogens and for elevated cell counts indicating inflammation or cancer. Usually done under the same anaesthetic as the MRI, which is part of why the two are quoted together. Abdominal ultrasound where an extracranial cause is suspected: For the reactive-seizure branch. A portosystemic liver shunt or an insulin-secreting pancreatic tumour causes seizures in a brain that will image normally, and neither is found by a neurological examination.
Does pet insurance cover seizures and epilepsy in dogs?
Dog Ultrasound is normally covered by an accident-and-illness policy taken out before the signs started. Diagnostic imaging ordered to investigate a covered illness or accident is reimbursable under a standard accident-and-illness policy - Embrace lists diagnostic testing for covered illnesses including biopsies, X-rays and MRIs, and carriers generally treat ultrasound the same way. The scan follows the condition: if the underlying problem turns out to be pre-existing or excluded, the imaging that diagnosed it is excluded too. A screening ultrasound with no clinical signs is preventive care and is not covered. No carrier we checked names ultrasound explicitly in its published coverage wording.
What is the outlook for a pet with seizures and epilepsy in dogs?
Cornell: many dogs achieve good seizure control with antiepileptic drugs, but complete disappearance of all seizure activity is rare and lifelong medication is typically necessary once management starts. Merck puts drug resistance at approximately one third of idiopathic epilepsy patients; Cornell's Dr Peter Early gives approximately 20% requiring more than one antiepileptic medication. Some dogs develop tolerance over time as the liver metabolises the drug faster, forcing higher doses and stronger side effects. Merck notes that status epilepticus is a serious challenge and usually carries a guarded to poor prognosis. Cornell also raises a question the literature has not settled: dogs show abnormal MRI lesions after a seizure — post-ictal changes thought to be a mix of cellular damage, stress and swelling — and while these reverse with time in humans, whether the same is true in dogs needs further study.
Can seizures and epilepsy in dogs be prevented?
Idiopathic epilepsy cannot be prevented, but three things reduce the number of seizures a dog has. Remove the toxins on Cornell's list from reach — dark chocolate, caffeine, xylitol, antifreeze, rat poison and alcohol. Give medication on time, every time, because missed doses are a common cause of what looks like drug failure. And use the seizure log to find triggers: Merck reports a study finding seizure-precipitating factors present in approximately 74% of cases, most frequently stress, sleep deprivation, weather changes and hormonal fluctuations, several of which are manageable. During a seizure itself, Cornell's safety instructions are to clear breakable or falling objects away, stay below the dog on stairs if you can do so safely, and keep away from the mouth — a dog is not aware of its surroundings during a seizure and may be disoriented or aggressive for minutes to hours afterwards.
What does dog seizure look like?
A burst of abnormal electrical activity in the brain, which in its classic form drops the dog on its side with stiff, paddling limbs, frothing, loss of consciousness and often loss of bladder and bowel control. Costs for seizures and epilepsy in dogs run from $56 for routine vet checkup (wellness exam) to $880 for dog ultrasound. A severe case can run past the top of that range — what treatment adds depends on how bad it gets.

How common is epilepsy in dogs, really?
Merck's summary of published studies gives 0.5% to 0.82% in nonreferral populations and 1% to 2.6% in referral hospital settings.
When does medication actually start?
Here our sources disagree, and we are publishing all three rather than picking one. Cornell's written guidance is that antiepileptic drugs are generally recommended for more than two seizures in six months. Cornell's Dr Early gives a rule of thumb of more than one seizure a month. Merck says medication is often started after the second or third documented seizure, typically more than two in a six-month period.
Was it actually a seizure?
The vet's first job, and the reason the video matters. Dr Early names the two events most often mistaken for one: a vestibular episode, which shows loss of balance, incoordination, head tilt and nystagmus, and an intermittent cardiac arrhythmia, where the collapse is softer, more like fainting, with a quicker recovery.
What happens if the medication does not work?
It happens often enough to plan for. Merck puts drug resistance at approximately one third of idiopathic epilepsy patients; Cornell's Dr Early puts the proportion needing more than one antiepileptic medication at approximately 20%.

What treating it costs, procedure by procedure
- veterinary urgent care visit cost $85–$150 — A same-day visit for a problem that cannot wait for an appointment but is not life-threatening, priced between a routine exam and an emergency-room exam at every clinic that publishes all three.
- routine vet checkup (wellness exam) cost $56–$130 — The annual physical examination a healthy dog or cat gets - vitals, ears, eyes, mouth, coat and skin - priced as the exam fee alone, before any test or vaccine is added to the bill.
- dog ultrasound cost $383–$880 — An ultrasound scan for a dog, most often a full abdominal study, sometimes with sedation and an ultrasound-guided sample taken at the same time.
- dog euthanasia cost $110–$750 — Veterinary euthanasia for a dog, carried out either in a clinic or at home by a mobile veterinarian, usually with sedation beforehand.
Related conditions
- dog dementia treatment — An age-related degenerative brain disease that Cornell describes as causing deterioration similar to Alzheimer's disease in people, with beta-amyloid accumulating and neurons dying.
- dog colitis medication — Inflammation of the colon, which shows up as small, frequent, urgent stools carrying mucus and often fresh red blood, with straining.
- dehydrated dog treatment — Dehydration is not a disease, it is the measurable consequence of one, and the numbers behind it are published rather than guessed.
- dog diabetic symptoms — The pancreas stops making enough insulin, so glucose stays in the blood instead of feeding the cells, spills into the urine and drags water with it.
- dog diarrhea — Loose or watery stool, with or without blood, and the sixth most frequently recorded disorder in dogs in primary practice.
- dog pregnancy symptoms — The signs owners read as pregnancy - weight gain, a swollen belly, mammary enlargement, milk, nesting behaviour - are produced just as reliably by a false pregnancy, and there is no home test that tells them apart.
- dog UTI symptoms — A bacterial infection of the bladder, usually Escherichia coli travelling up the urethra from the perineum.
- dog vomiting and diarrhea — Sudden vomiting, usually with diarrhoea, from an inflamed stomach and intestine.
- dog vomiting blood — Blood in a dog's vomit - fresh red, dark clots, or the brown grit that looks like coffee grounds because the stomach has already digested it.
- parvo in dogs — A virus that destroys the lining of a puppy's intestine and the bone marrow that makes its white blood cells, producing vomiting and bloody diarrhoea that can kill in days.
- dog vomiting yellow — Yellow vomit is bile that has refluxed from the duodenum back into an empty stomach, and it is a description rather than a diagnosis.
- dog coughing — A cough is a sign, not a diagnosis, and the same dry hack can come from an infection that clears itself in two weeks or from a failing heart valve.
- dog ear infection treatment — Inflammation of the ear canal, almost always with a yeast or bacterial overgrowth on top of it.
- dog eye allergies — A red, weeping, itchy eye is what owners call an eye allergy, and environmental irritants and allergens genuinely are, in Merck's words, common causes of conjunctivitis in all species.
- hip dysplasia in dogs — An inherited malformation in which the hip joint is too loose, so the ball grinds in the socket and arthritis follows.
- ivdd in dogs — A disc between the vertebrae ruptures or bulges and presses on the spinal cord, causing pain, wobbliness or paralysis.
- kennel cough in dogs — A contagious inflammation of the windpipe and airways caused by a mix of viruses and bacteria, not by one organism.
- dog limping — Limping means something painful is interfering with the normal use of a limb, and Cornell's framing is that it deserves veterinary attention rather than a wait-and-see.
- staph infection in puppies — Crusty pustules on a puppy's hairless belly and groin, caused by the dog's own resident bacterium overgrowing.
- dog wound treatment — Cleaning and closing a wound is mostly a timing decision, and the two things owners get wrong are both correctable in the first hour.

- kidney disease in cat symptoms — The kidneys lose function slowly and permanently, and the cruel arithmetic is that they hide it until most of them are gone.
- signs and symptoms of cat diabetes — A disease in which the cat's cells stop responding properly to insulin, so glucose stays in the blood instead of feeding the body.
- why is my cat meowing so much — Excessive meowing is a sign, not a disease, and it is the sign this dataset can be most useful about — because its differentials range from a cat that has learned meowing produces breakfast to a male cat that cannot pass urine and will die within about two days without treatment.
- cat coughing — A cough in a cat is a lower-airway problem until proved otherwise, and the commonest cause is asthma - an allergic narrowing of the small airways that Cornell puts at 1 to 5% of cats.
- urinary blockage cat — A group of conditions causing painful, frequent, bloody or unproductive urination in cats.
- worm cat symptoms — Worms in cats are usually silent, and the signs owners are told to look for - a dull coat, a potbelly, vomiting, diarrhoea - are the same signs as a dozen other things.
- symptoms of blocked anal glands in dogs — Two small scent sacs sit either side of the anus and normally empty when a dog passes a firm stool.
