Dog Diabetic Symptoms: The Four Signs and What Treatment Costs

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. This is an emergency and needs a vet now if any of these are true: Vomiting, not eating, and profound weakness or wobbliness in a dog that has been drinking heavily; Breath that smells sweet or like nail polish remover.

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.

  1. Emergency — go nowGo to an emergency vet or the nearest open clinic now. Do not wait for morning.
    • Vomiting, not eating, and profound weakness or wobbliness in a dog that has been drinking heavily
    • Breath that smells sweet or like nail polish remover
    • Rapid, deep breathing, or collapse
    • A diagnosed diabetic dog that has become disoriented, trembling, or has had a seizure
    • A diabetic dog that has had its insulin but has not eaten, and is now weak or unsteady

    Two different emergencies sit on this rung and they need opposite treatments, which is why neither is a home problem. Diabetic ketoacidosis is decompensated diabetes: Merck describes ketoacids and glucose accumulating in the blood with dehydration, hypovolaemia, metabolic acidosis, electrolyte disturbance, azotaemia, vomiting and anorexia, and calls the disturbance profound and life-threatening. Low blood sugar from too much insulin, too little food or vomiting after a dose is the mirror image and produces trembling, disorientation, collapse and seizures. Do not guess between them at home - phone the clinic and go.

  2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
    • A dog that has suddenly started drinking and urinating far more than usual
    • Weight loss despite a normal or increased appetite
    • Urinating in the house in a previously clean dog
    • Cloudiness appearing in both eyes over days to weeks
    • A newly diagnosed diabetic whose signs are not settling on treatment

    These are the classic signs Merck lists - polyuria, polydipsia, polyphagia, weight loss, cataracts and weakness - and the reason they warrant a same-day appointment rather than a routine one is that the diagnosis is cheap and immediate. Merck's renal threshold for glucose in dogs is about 180 mg/dL, so a urine dipstick and a blood glucose in the consulting room usually answer the question the same afternoon, before the dog reaches ketoacidosis.

  3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
    • Recurring urinary or skin infections in a middle-aged dog
    • A stable diabetic dog due for its regular glucose reassessment
    • An overweight dog, or one on long-term steroids, with no signs yet

    Merck notes diabetic animals have decreased resistance to bacterial and fungal infection and often develop recurrent cystitis, prostatitis, bronchopneumonia and dermatitis, so a dog on its third course of antibiotics for a urinary infection is worth a glucose test. For an established diabetic, Merck's schedule once stable on maintenance treatment is reassessment every 4 to 6 months.

  4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
    • An entire female dog, especially in the weeks after a season
    • A dog on long-term corticosteroids or progestins
    • A dog of a predisposed breed with no signs

    Merck: insulin resistance and secondary diabetes occur in dogs with spontaneous hyperadrenocorticism and in dogs given corticosteroids or progestins long term, and pregnancy and dioestrus also predispose - in dogs, but not cats, progesterone releases growth hormone from mammary tissue, causing hyperglycaemia and insulin resistance. That is a concrete argument for spaying, and it is the one modifiable item on this list.

Four signs define canine diabetes: drinking more, urinating more, eating more, and losing weight while doing all three. The one that actually brings dogs in is often none of them.

The sign owners notice first is usually the eyes

Cloudiness appearing in both eyes over days to weeks is frequently the first thing a household registers, because the drinking and the weight loss build slowly enough to be absorbed. Merck reports cataracts develop frequently in dogs with poorly controlled diabetes.

The scale of the association is unusual. In a primary-care study of 134,329 Australian dogs, diabetic dogs had odds of cataracts 9.80 times those of non-diabetic dogs. That is an odds ratio from one national dataset rather than a risk for your dog, but it is large enough to be the practical headline.

The mechanism is not ageing. Merck describes diabetic cataracts forming along the suture lines of the lens fibres in a stellate pattern, driven by the sorbitol pathway — which is why they can appear in a young dog and appear fast.

The blindness they cause is, unlike the diabetes, correctable. Lens removal is an option in suitable dogs, and the cost of dog eye surgery is in the section below, because it is the single most likely surgical event in a diabetic dog's life and almost nobody warns owners it is coming.

The diagnosis is a dipstick and a blood glucose

This is one of the cheapest diagnoses in veterinary medicine, which is why the signs above are a same-day appointment rather than a routine one.

Merck's diagnosis rests on documenting persistent high blood glucose together with glucose in the urine, and the canine renal threshold is about 180 mg/dL — so glucose in the urine of a dog that is drinking heavily and losing weight is close to diagnostic in the consulting room, that afternoon.

The reason not to wait for the appointment slot next week is what happens between. Ketoacidosis is the decompensated form of the same disease, and the gap between "diagnosed on a dipstick" and "admitted overnight" is usually days.

Dogs do not go into remission

This is the difference that shapes the whole budget. Merck is explicit: in cats, remission is possible; in dogs, absent a predisposing disease, diabetes is generally lifelong.

So the treatment is insulin twice daily with diet modification for the rest of the dog's life, reassessed every four to six months once stable. There is no version of this where a good few months means the injections stop, and reading feline material — where remission is a realistic goal — sets the wrong expectation. Feline diabetes is a genuinely different disease in that one respect.

Consistency is the treatment as much as the drug. The same food, the same amount, at the same times relative to the injection, every day, because an insulin dose is only meaningful against a stable feeding pattern.

Home glucose monitoring is the cheapest item on the list and the one with real evidence behind it. Merck cites studies in both dogs and cats showing at-home monitoring improves glycaemic control, and recommends it specifically to avoid the stress of in-hospital testing distorting the readings.

The diseases that travel with it

Canine diabetes rarely arrives alone, and the company it keeps is expensive. In the same Australian cohort, suspected pancreatitis carried odds of 10.58 and hyperadrenocorticism — Cushing's — odds of 6.21 in diabetic dogs.

That is consistent with the mechanism. Merck describes islet cell destruction by immune attack or by severe pancreatitis, with chronic relapsing pancreatitis destroying both the digestive and hormonal parts of the pancreas and replacing them with fibrous tissue.

The practical version: a diabetic dog whose insulin requirement keeps climbing usually has something underneath it. Merck names spontaneous hyperadrenocorticism, long-term corticosteroids or progestins, pregnancy and dioestrus as causes of insulin resistance, and each has its own treatment.

Is spaying worth it for a female dog?

For diabetes specifically, yes, and the mechanism is canine rather than general. Merck describes progesterone releasing growth hormone from mammary tissue in dogs — but not cats — causing high blood glucose and insulin resistance, with pregnancy and dioestrus predisposing.

That makes spaying the one clearly modifiable route into this disease, and spaying an already-diabetic female removes a driver of resistance rather than just preventing a future problem.

One finding from the Australian data cuts against the usual teaching and is worth carrying carefully. In that population, desexed male dogs had higher odds of diabetes than entire males and than desexed females — the opposite of the female predisposition reported elsewhere — and the authors called for further investigation rather than treating it as settled. We are repeating it as an unresolved finding, not as advice.

Two emergencies that need opposite treatments

A diabetic dog can be in crisis from too much glucose or too little, and the correct response to each is the reverse of the other. Neither is a home problem.

Diabetic ketoacidosis is decompensated diabetes. Merck describes ketoacids and glucose accumulating in the blood with dehydration, hypovolaemia, metabolic acidosis, electrolyte disturbance, azotaemia, vomiting and anorexia, and calls the disturbance profound and life-threatening. Sweet or nail-polish-remover breath, rapid deep breathing and collapse belong here.

Low blood sugar is the mirror image, and its usual cause is mundane: a dog that had its insulin and then did not eat, or vomited afterwards. Trembling, disorientation, wobbliness, collapse and seizures.

Why ketoacidosis is hospital work is visible in Merck's own protocol: blood glucose measured every one to two hours, and not allowed to fall by more than 50 to 100 mg/dL per hour, because a faster drop risks cerebral oedema. That is not something to attempt at home, and it is the reason the emergency visit is priced below. The dehydration that comes with it has its own page.

A dog on its third course of antibiotics deserves a glucose test

Merck notes diabetic animals have decreased resistance to bacterial and fungal infection and often develop recurrent cystitis, prostatitis, bronchopneumonia and dermatitis.

That inverts the usual order of suspicion. Recurrent urinary or skin infections in a middle-aged dog are a reason to check the glucose, not just to repeat the antibiotic — and the test costs a fraction of the third course.

Breed is a weaker signal but worth knowing. Merck names Yorkshire Terriers, Border Terriers, Cavalier King Charles Spaniels, Bichon Frises and West Highland White Terriers as predisposed; the Australian study found the highest odds in Australian Terriers, Siberian Huskies and English Springer Spaniels, with lower risk in German Shepherds, Golden Retrievers and Boxers. The two lists do not fully agree, and we have not merged them.

What it costs, and the number we do not publish

The section below prices four real things: the consultation where this is diagnosed and then reassessed every four to six months, the emergency admission for ketoacidosis, abdominal ultrasound to find the pancreatitis or adrenal disease underneath, and cataract surgery.

What it does not price is the largest number in this disease: insulin, syringes, glucose test strips and monitoring for the rest of the dog's life. We do not yet publish a researched recurring-cost record for canine diabetes, and we are not going to imply the exam fee is what diabetes costs.

Plan for the shape. A modest diagnosis, a small but permanent monthly cost that never stops, twice-yearly rechecks — and two potential large events, the ketoacidosis admission and the eye surgery, which are the ones worth insuring against before the diagnosis exists rather than after.

Why diabetes in dogs (diabetes mellitus) happens

Destruction of the insulin-producing cells
Merck: the mechanisms are multiple but usually involve destruction of the islet cells, either by immune attack or by severe pancreatitis in dogs. Chronic relapsing pancreatitis destroys both the digestive and hormonal parts of the pancreas and replaces them with fibrous tissue. The Australian primary-care study found suspected pancreatitis was the strongest comorbidity association, at ten and a half times the odds.
Hormones that fight insulin
Merck: dogs with spontaneous hyperadrenocorticism, or given corticosteroids or progestins long term, develop insulin resistance and secondary diabetes. Pregnancy and dioestrus predispose too, because in dogs progesterone triggers growth hormone release from mammary tissue. The Australian study put the odds of concurrent hyperadrenocorticism in a diabetic dog at 6.2 times.
Breed and genetics
Merck names small breeds - Yorkshire Terrier, Border Terrier, Cavalier King Charles Spaniel, Bichon Frise, West Highland White Terrier - as predisposed, while noting any breed can be affected. The Australian primary-care study of 134,329 dogs found the highest odds in Australian Terriers, Siberian Huskies and English Springer Spaniels, and lower risk in German Shepherds, Golden Retrievers and Boxers.
Obesity
Merck: obesity predisposes both dogs and cats to insulin resistance, and stress, obesity and corticosteroid or progestogen administration may increase the severity of clinical signs. It is not the primary cause in dogs the way it is in cats, but it is the one an owner can change.
Age and sex
Merck: most cases of spontaneous diabetes occur in middle-aged dogs. The Australian study found something that runs against the usual teaching and is worth flagging as such - desexed male dogs there had higher odds of diabetes than entire males and than desexed females, in contrast to other populations where females are predisposed, and the authors call for further investigation rather than treating it as settled.

How a vet diagnoses diabetes in dogs (diabetes mellitus)

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.

Physical examination, urine dipstick and blood glucose
Merck: diagnosis rests on documenting persistent hyperglycaemia together with glucose in the urine. Merck's canine renal threshold of roughly 180 mg/dL is why glucose in the urine of a dog that is drinking and losing weight is close to diagnostic in the consulting room. What it costs
Full blood count, biochemistry and urine culture
Finds the complications and the causes that come with it: kidney values, liver enzymes, electrolytes, evidence of pancreatitis, and the urinary infections Merck says diabetic dogs are prone to. It also establishes the baseline against which the first months of insulin are judged.
Blood ketones or urine ketone testing
Separates a stable new diabetic from a dog sliding into ketoacidosis, which is the difference between starting insulin as an outpatient this week and being hospitalised tonight.
Abdominal ultrasound
Looks for the pancreatitis, adrenal disease and liver change that sit behind a large share of canine diabetes, and for the uterine infection that can drive insulin resistance in an entire female dog. What it costs
Ophthalmic examination
Merck describes diabetic cataracts in dogs as forming along the suture lines of the lens fibres in a stellate pattern, driven by the sorbitol pathway rather than by age. Establishing whether the lens is already involved decides whether cataract surgery is on the table, and how urgently. What it costs

How diabetes in dogs (diabetes mellitus) is treated

Emergency treatment of diabetic ketoacidosis
Intravenous fluids, electrolyte correction and a carefully titrated insulin infusion in hospital. Merck's cautions define why this is not a home job: blood glucose is measured every one to two hours, and it must not be allowed to fall by more than 50-100 mg/dL per hour, because a faster drop risks cerebral oedema. What emergency treatment of diabetic ketoacidosis costs
Insulin, twice daily, for life
Merck: in both dogs and cats the treatment is insulin with diet modification, and lente is the insulin of choice for dogs. Merck is clear about the difference from cats, and it is the fact that shapes the whole cost of this disease: remission is possible in cats, but in dogs the disease, in the absence of a predisposing disease, is generally lifelong. Doses are set and adjusted by the vet for the individual dog. What insulin, twice daily, for life costs
Diet and routine
Merck pairs diet modification with insulin as the treatment, not as an optional extra. The practical part is consistency - the same food, the same amount, at the same times relative to the injection, every day - because insulin doses are only meaningful against a stable feeding pattern.
Home glucose monitoring
Merck: clinical signs and serial blood glucose readings guide treatment after initial stabilisation at home over 5 to 7 days, and testing is best done at home to avoid the stress of in-hospital testing. Merck cites studies in both dogs and cats showing that at-home monitoring improves glycaemic control, and lists it among the key points of the entry. It is also the cheapest thing on this list.
Cataract surgery
Merck describes diabetic cataracts as frequent in dogs with poorly controlled disease, and unlike the diabetes itself, the blindness they cause is surgically correctable by lens removal in suitable dogs. This is the line that turns a chronic drug cost into a four-figure one, and it is the single most likely surgical event in a diabetic dog's life. What cataract surgery costs
Treating what is driving the insulin resistance
Merck: spaying an entire female removes the progesterone effect, stopping or reducing corticosteroids removes another, and treating hyperadrenocorticism or pancreatitis removes a third. A diabetic dog whose insulin dose keeps climbing usually has one of these underneath it. What treating what is driving the insulin resistance costs

Outlook and prevention

A dog diagnosed before ketoacidosis, whose owner can inject twice a day and keep a routine, can live years with a good quality of life on insulin. Merck's blunt distinction from cats is the one that shapes expectations and budget: remission is possible in cats, but in dogs the disease, absent a predisposing disease, is generally lifelong, so this is a recurring cost rather than a course of treatment. Merck reassesses stable dogs every 4 to 6 months. The two things most likely to change the picture are cataracts, which Merck says develop frequently in poorly controlled dogs and which the Australian primary-care data put at nearly ten times the odds, and ketoacidosis, which Merck describes as profound and life-threatening. Hyperosmolar hyperglycaemic state is less common than ketoacidosis and Merck reports its prognosis is worse.

Type 1-like diabetes in a genetically predisposed dog cannot be prevented, but three of the routes into it can be narrowed. Keep the dog lean, because Merck lists obesity as predisposing both species to insulin resistance. Spay entire females, because Merck describes progesterone-driven growth hormone release as a canine-specific cause of insulin resistance and dioestrus and pregnancy as predisposing. And avoid unnecessary long courses of corticosteroids and progestins, which Merck names directly. Beyond that, prevention becomes early detection: drinking more, urinating more, eating more and losing weight are cheap to test for and expensive to miss, and a urine dipstick costs a fraction of a night in hospital.

Does pet insurance cover diabetes in dogs (diabetes mellitus)?

Dog Eye Surgery is normally covered by a standard accident-and-illness policy. This depends more on the carrier than on the operation. Cherry eye and entropion are breed-linked and often present in young dogs, so they are the classic hereditary-condition test case: ASPCA Pet Health Insurance lists eye disorders among the hereditary and congenital conditions its standard plan covers, and Embrace covers hereditary conditions when not pre-existing. A dog whose eye was already noted as abnormal at a puppy check will normally be declined for that eye. Cataracts secondary to diabetes are usually claimable as a complication of a covered illness; age-related cataracts in an older dog often are not.

What you would get back: 70-90% of the covered bill after the deductible, where the carrier covers hereditary conditions and the eye was healthy at enrolment.

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 diabetes in dogs (diabetes mellitus) — 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–$6,700 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 eye surgery shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.

Common questions

Is diabetes in dogs (diabetes mellitus) an emergency?

Treat it as an emergency if any of these are true: Vomiting, not eating, and profound weakness or wobbliness in a dog that has been drinking heavily; Breath that smells sweet or like nail polish remover; Rapid, deep breathing, or collapse; A diagnosed diabetic dog that has become disoriented, trembling, or has had a seizure; A diabetic dog that has had its insulin but has not eaten, and is now weak or unsteady. Two different emergencies sit on this rung and they need opposite treatments, which is why neither is a home problem. Diabetic ketoacidosis is decompensated diabetes: Merck describes ketoacids and glucose accumulating in the blood with dehydration, hypovolaemia, metabolic acidosis, electrolyte disturbance, azotaemia, vomiting and anorexia, and calls the disturbance profound and life-threatening. Low blood sugar from too much insulin, too little food or vomiting after a dose is the mirror image and produces trembling, disorientation, collapse and seizures. Do not guess between them at home - phone the clinic and go.

How much does it cost to treat diabetes in dogs (diabetes mellitus)?

Costs for diabetes in dogs (diabetes mellitus) run from $56 for routine vet checkup (wellness exam) to $6,700 for dog eye surgery. Which of the 4 procedures below your animal needs is what decides where you land.

How is diabetes in dogs (diabetes mellitus) diagnosed?

Physical examination, urine dipstick and blood glucose: Merck: diagnosis rests on documenting persistent hyperglycaemia together with glucose in the urine. Merck's canine renal threshold of roughly 180 mg/dL is why glucose in the urine of a dog that is drinking and losing weight is close to diagnostic in the consulting room. Full blood count, biochemistry and urine culture: Finds the complications and the causes that come with it: kidney values, liver enzymes, electrolytes, evidence of pancreatitis, and the urinary infections Merck says diabetic dogs are prone to. It also establishes the baseline against which the first months of insulin are judged. Blood ketones or urine ketone testing: Separates a stable new diabetic from a dog sliding into ketoacidosis, which is the difference between starting insulin as an outpatient this week and being hospitalised tonight. Abdominal ultrasound: Looks for the pancreatitis, adrenal disease and liver change that sit behind a large share of canine diabetes, and for the uterine infection that can drive insulin resistance in an entire female dog. Ophthalmic examination: Merck describes diabetic cataracts in dogs as forming along the suture lines of the lens fibres in a stellate pattern, driven by the sorbitol pathway rather than by age. Establishing whether the lens is already involved decides whether cataract surgery is on the table, and how urgently.

Does pet insurance cover diabetes in dogs (diabetes mellitus)?

Dog Eye Surgery is normally covered by an accident-and-illness policy taken out before the signs started. This depends more on the carrier than on the operation. Cherry eye and entropion are breed-linked and often present in young dogs, so they are the classic hereditary-condition test case: ASPCA Pet Health Insurance lists eye disorders among the hereditary and congenital conditions its standard plan covers, and Embrace covers hereditary conditions when not pre-existing. A dog whose eye was already noted as abnormal at a puppy check will normally be declined for that eye. Cataracts secondary to diabetes are usually claimable as a complication of a covered illness; age-related cataracts in an older dog often are not.

What is the outlook for a pet with diabetes in dogs (diabetes mellitus)?

A dog diagnosed before ketoacidosis, whose owner can inject twice a day and keep a routine, can live years with a good quality of life on insulin. Merck's blunt distinction from cats is the one that shapes expectations and budget: remission is possible in cats, but in dogs the disease, absent a predisposing disease, is generally lifelong, so this is a recurring cost rather than a course of treatment. Merck reassesses stable dogs every 4 to 6 months. The two things most likely to change the picture are cataracts, which Merck says develop frequently in poorly controlled dogs and which the Australian primary-care data put at nearly ten times the odds, and ketoacidosis, which Merck describes as profound and life-threatening. Hyperosmolar hyperglycaemic state is less common than ketoacidosis and Merck reports its prognosis is worse.

Can diabetes in dogs (diabetes mellitus) be prevented?

Type 1-like diabetes in a genetically predisposed dog cannot be prevented, but three of the routes into it can be narrowed. Keep the dog lean, because Merck lists obesity as predisposing both species to insulin resistance. Spay entire females, because Merck describes progesterone-driven growth hormone release as a canine-specific cause of insulin resistance and dioestrus and pregnancy as predisposing. And avoid unnecessary long courses of corticosteroids and progestins, which Merck names directly. Beyond that, prevention becomes early detection: drinking more, urinating more, eating more and losing weight are cheap to test for and expensive to miss, and a urine dipstick costs a fraction of a night in hospital.

What should I know about diabetes in dogs (diabetes mellitus)?

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. Costs for diabetes in dogs (diabetes mellitus) run from $56 for routine vet checkup (wellness exam) to $6,700 for dog eye surgery. Which of the 4 procedures below your animal needs is what decides where you land.

Is spaying worth it for a female dog?

For diabetes specifically, yes, and the mechanism is canine rather than general. Merck describes progesterone releasing growth hormone from mammary tissue in dogs — but not cats — causing high blood glucose and insulin resistance, with pregnancy and dioestrus predisposing.

What treating it costs, procedure by procedure

  • 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.
  • 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.
  • 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 eye surgery cost $300–$6,700 Ophthalmic surgery in a dog, covering cherry eye and entropion correction at one end and cataract removal by phacoemulsification or eye removal at the other.

Related conditions

  • 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 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.
  • 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.
  • 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 seizures 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.
  • 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 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 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.
  • 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.
  • dog skin yeast infection Malassezia yeast lives on normal dog skin and only causes disease when something changes the skin it lives on.
  • 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.
  • dog skin allergies A lifelong immune reaction to ordinary environmental substances - pollens, moulds, dust mites, dander - that shows up as itching rather than sneezing.
  • worms in dogs Four different worms with four different stories, grouped together only because they all live in a dog's gut.
  • ringworm in dogs Ringworm is a fungal infection of the hair and the surface of the skin, and the name is the first thing that misleads.
  • yeast infection in dogs Malassezia pachydermatis is a yeast that lives on normal dog skin and in normal ears.
  • cat teeth disease Three overlapping diseases, not one: gingivitis, which is reversible; periodontitis, which is not; and tooth resorption, in which the tooth dissolves from the inside out and which Cornell calls the most common cause of tooth loss in cats.
