Dog Limping: When to Worry, and What It Costs to Fix

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. This is an emergency and needs a vet now if any of these are true: Refusing to put any weight on a leg after being hit by a car, a fall, or a fight; A limb at an obvious wrong angle, or a wound with bone visible.

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.
   • Refusing to put any weight on a leg after being hit by a car, a fall, or a fight
   • A limb at an obvious wrong angle, or a wound with bone visible
   • Dragging the back legs, knuckling over onto the tops of the paws, or a wobbly drunken gait
   • Sudden severe pain with pale gums, a swollen belly or collapse
   • A hot, grossly swollen limb or joint in a dog that is also feverish and will not stand

   Two of these are not orthopaedic at all, and that is the point of putting them first. Merck's rule is that musculoskeletal disorders do not typically cause ataxia, so a dog showing ataxia, abnormal proprioception or abnormal spinal reflexes has a neurological problem until proved otherwise - which is the intervertebral disc disease pathway, where the difference between operating today and operating tomorrow is measured in whether the dog walks again. Sudden severe pain with pale gums can be a pathological fracture through a bone tumour or bleeding from elsewhere.

2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
   • Sudden refusal to bear weight with no trauma at all
   • A single joint that is hot, swollen and painful to touch
   • Lameness that moves from leg to leg, especially with a fever or lethargy
   • A limp in a dog that is also off food, feverish, or unwilling to move at all
   • A young large-breed dog that goes acutely and severely lame

   A hot, painful single joint is septic arthritis until cultured, and Merck's instruction is that fluid from arthrocentesis goes for both analysis and culture - while noting a culture-negative result does not completely rule out joint infection. Shifting-leg lameness with systemic signs points at immune-mediated polyarthritis or a tick-borne infection, both of which are treated medically and neither of which improves on rest and an anti-inflammatory.

3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
   • A limp that has lasted more than a day or two
   • Difficulty with stairs, jumping into the car, or rising from a lie-down
   • Sitting with one leg kicked out to the side - the 'positive sit test'
   • Muscle wasting on one hind leg, or a firm swelling on the inside of the shin
   • A clicking or popping noise from the knee
   • Stiffness that is worst after rest and eases with movement

   Cornell's bottom line: if your dog has been limping for more than a day or two, or if the pain is severe, sudden or worsening, do not wait. This rung is where cruciate disease is usually caught, and ACVS's description of it is the reason waiting does not help - rupture is the result of slow degeneration rather than a sudden injury to a healthy ligament, and partial tears are common and almost always progress to a full tear over time. Take a video of the limp at home: Cornell notes some dogs move normally at the clinic on adrenaline, and videos provide information the exam cannot.

4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
   • A mild limp after an unusually long or rough walk, in a bright dog that is eating normally and still bearing weight
   • A limp that is already improving within the first 24 hours on strict rest

   Lead-only, no stairs, no jumping, no running for a day or two, and watch it. Anything that persists past 48 hours, worsens, or involves any of the signs above moves up the ladder. Do not reach for a human painkiller while you wait - ibuprofen, naproxen and paracetamol are all toxic to dogs at ordinary human doses, and an anti-inflammatory given before the exam also masks the pain response the vet needs to find the problem.

Most limps get diagnosed by two facts the owner already knows: how old the dog is, and which leg it is. Cornell's framing is that in an older dog the commonest cause of hind-limb lameness is a torn cranial cruciate ligament, and in a young large-breed dog it is hip dysplasia. Two diseases, two operating tables, two very different bills.

When a limp is not an orthopaedic problem at all

Some of the signs at the top of the ladder above are not limb injuries. A dog that is knuckling over onto the tops of its paws, dragging its back legs or walking like a drunk is showing ataxia, and Merck's rule is that musculoskeletal disorders do not typically cause it.

That means a neurological problem until proved otherwise, and the usual candidate is a ruptured disc. It matters because the clock runs differently: intervertebral disc disease is graded by whether the dog can still feel a firm pinch in its toes, and the odds of walking again fall while you decide.

The other non-orthopaedic entry is a sudden non-weight-bearing lameness with pale gums and severe pain. That can be a fracture through a bone weakened by a tumour, or bleeding from somewhere else entirely.

Why waiting on a cruciate tear does not help

A torn knee ligament in a dog is not a sports injury. ACVS describes cruciate rupture as the end of a slow degeneration rather than a single trauma, driven by genetics, conformation, poor conditioning and body weight.

Partial tears are common, and ACVS says they almost always progress to a full tear over time. So a dog that improves on two weeks of rest has not healed. It has become comfortable on a knee that is still unstable, and ACVS is blunt about what pain medication buys in that state: comfort, not stability.

The meniscus is frequently damaged as well, which is the part that turns an intermittent limp into a click and a yelp.

Will the other knee go too?

Usually, and this is the number to have before agreeing to the first operation. ACVS reports that 40 to 60% of dogs with cruciate disease in one knee develop it in the other, and that up to half of those do so within 12 to 18 months of diagnosis.

Set against the good news — ACVS puts significant improvement after surgical repair at 85 to 90%, with arthritis progressing more slowly than under medical management — it changes the arithmetic rather than the decision. Budgeting for one knee and being handed two is the commonest financial surprise in canine orthopaedics, and nobody quotes it that way at the consult.

My dog is limping but shows no sign of pain

Dogs mask pain from strangers, and adrenaline does the rest. Cornell notes that some dogs move normally at the clinic and recommends filming the limp at home, because a video carries information the examination cannot.

There is also a category of limp with genuinely little pain attached: a mild mechanical lameness from a low-grade luxating patella, or the sit-with-one-leg- kicked-out posture that is often the first sign of cruciate disease. Neither is an emergency and neither improves on being ignored.

The cause most often missed is not in the leg at all. Merck describes interdigital furuncles — painful nodules in the webbing between the toes — as making dogs obviously lame on that foot, and a broken nail, a grass awn or a cut pad does the same. Check the foot before you buy a brace.

The one intervention with better evidence than anything sold in a bottle

Keeping the dog lean, and it is not close. In a lifetime paired-feeding study of 48 Labradors, the hip-joint arm found the median age at first radiographic evidence of hip osteoarthritis was 6 years in the control-fed dogs and 12 years in the pair-mates fed 25% less.

That is a whole dog's middle age, bought with a measuring cup. ACVS names excess weight and poor conditioning as cruciate risk factors an owner directly controls, and Cornell's mechanism for why it works twice over is that fat cells produce inflammatory mediators, so weight loss does more than the equivalent load reduction from a harness or a brace would.

Why "it seemed to help" is not evidence in this disease

Because it has been measured, and it was wrong about four times in ten. In the placebo arm of an FDA-approved trial of 58 dogs with lameness from osteoarthritis, owners judged their dog improved 39.7% of the time and veterinarians 43 to 45% of the time, while force-plate measurement showed no change in 46 of the 58 dogs.

That caregiver placebo effect is not a comment on supplements specifically. It applies to braces, to laser sessions, to joint diets and to any outcome reported by the person paying for it. It is the reason a persistent limp gets a radiograph rather than a repeat purchase.

The limps that are infections, not injuries

A single joint that is hot, swollen and painful to touch is septic arthritis until cultured. Merck's instruction is that fluid from arthrocentesis goes for both analysis and culture, and it adds a caution worth carrying into the conversation: a culture-negative result does not completely rule out joint infection.

A lameness that moves from leg to leg is the other one, especially with a fever or lethargy. That points at immune-mediated polyarthritis or a tick-borne infection — Lyme disease is the classic version — and neither improves on rest and an anti-inflammatory. Merck's point is structural: until an underlying systemic disease is addressed, the orthopaedic signs cannot be resolved.

Both of those are treated medically and both get worse on the plan a sprain would get. They are the reason the same-day rung above exists at all.

What actually happens at the appointment

Cornell describes it as watching before touching: the dog walked and trotted on different surfaces, in straight lines and in circles, because turning loads the inside limbs. Then palpation from the toe upward for pain, swelling, instability and reduced range of motion, and the spine as well.

ACVS notes a cruciate tear can be diagnosed on the hands-on examination alone, by eliciting cranial drawer or tibial thrust — and adds a nuance worth knowing before agreeing to films: radiographs are only required if surgery is being performed, for surgical planning, though they may support the exam in difficult cases.

The line most often left off a quote is sedation. Cornell notes some dogs are too anxious or too painful to tolerate a complete awake examination, and Merck that a sedated examination allows a more complete evaluation. It is a real cost and it is often the difference between a diagnosis and a guess.

Nine operations, one limp: where the money actually goes

This is the widest cost fan on the site, and that is the honest shape of the answer. The section below prices all nine procedures this record joins, from a $56 examination to a five-figure knee, because the limp does not tell you which one you are buying until it has been worked up.

Four ranges do most of the deciding. A cruciate repair is the commonest four-figure outcome — ACL surgery costs $1,000–$10,000 nationally, and the TPLO technique specifically runs $2,500–$7,500 with $3,525 typical. A fracture repair is the branch where one afternoon changes the bill by an order of magnitude. And leg amputation, at $735–$6,800, is on this list because a persistent limp in an older large-breed dog is how an osteosarcoma diagnosis nearly always starts.

Those cost pages price the operation. This page decides whether the operation is the question — and for a young large-breed dog that is bunny-hopping rather than limping on one leg, the answer is usually hip dysplasia and a different set of options entirely. The sedated examination is the line item most often left off a quote and most often the difference between a diagnosis and a guess.

Why limping in dogs (lameness) happens

Cranial cruciate ligament disease

Cornell names it the most common cause of hind-limb lameness in older dogs. ACVS: it is caused by ligament degeneration over time rather than a single trauma, with obesity, poor conditioning, genetics, conformation and breed contributing; the meniscus is frequently damaged as well. Rottweilers, Newfoundlands, Staffordshire Terriers, Mastiffs, Akitas, Saint Bernards, Chesapeake Bay Retrievers and Labradors are over-represented.

Hip dysplasia

Cornell names it the most common cause of hind-limb lameness in young dogs, particularly larger breeds, producing difficulty with stairs, jumping and getting into cars. It has its own page on this site because the treatment decision - conservative management versus surgery - is a separate and expensive question.

Osteoarthritis

Cornell: a chronic, progressive joint disease that is not confined to senior dogs and can develop at any age, especially where there is obesity or an underlying orthopaedic condition. Hip dysplasia, elbow dysplasia, patellar luxation, previous cruciate damage and old fractures all funnel into it, and fat cells produce inflammatory mediators that make it worse.

Developmental disease in young dogs

Cornell's young-dog lists: hind limb - hip dysplasia, panosteitis and hypertrophic osteodystrophy ('growing pains'), luxating patella, tendon and muscle injuries; front limb - elbow dysplasia, panosteitis and hypertrophic osteodystrophy, osteochondrosis, and shoulder problems. Merck adds that patellar luxation is graded and that the grade drives whether surgery is advised.

Fractures and soft-tissue injury

Cornell lists traumatic injury and foot injuries among the causes, and Merck covers muscular trauma and joint trauma in dogs and cats. A fracture is obvious; a torn muscle, a strained tendon or a cut pad is not, and it is a common reason a limp appears without any story to explain it.

Bone tumours

Cornell lists bone cancer (osteosarcoma) among the causes of both front and hind limb lameness in older dogs, and Merck covers bone tumours in dogs and cats. It is the reason a persistent limp in an older large-breed dog gets a radiograph rather than a repeat prescription, and the reason a sudden non-weight-bearing lameness with severe pain can be a pathological fracture.

Immune-mediated and infectious joint disease

Merck covers immune-mediated polyarthritis and septic arthritis in dogs and cats, and notes that until an underlying systemic disease is addressed the orthopaedic signs cannot be resolved. Lyme disease is the classic infectious version and produces shifting lameness with fever.

Paw and nail problems

The cause most often missed because the owner is watching the leg. Merck describes interdigital furuncles as painful nodules between the toes that make dogs obviously lame on the affected foot, and Cornell lists foot injuries and infections among the causes of hind-limb lameness in older dogs. A broken nail, a grass awn or a cut pad will produce a convincing limp.

How a vet diagnoses limping in dogs (lameness)

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.

History, gait observation and orthopaedic examination

Cornell's account of what actually happens at the appointment: watching the dog walk and trot on different surfaces, in straight lines and in circles, because turning loads the inside limbs; then palpating from the toe upward for pain, swelling, instability and reduced range of motion, plus the spine. ACVS notes a cruciate tear can be diagnosed on hands-on exam alone, by eliciting cranial drawer or tibial thrust. What it costs

Sedated examination

Cornell: some dogs are too anxious or painful to tolerate a complete awake exam, and the vet will decide whether anti-anxiety medication or sedation is needed. Merck notes a sedated examination allows a more complete evaluation. It is a real cost line and it is often the difference between a diagnosis and a guess.

Radiographs

Shows fractures, arthritic change, joint effusion and the aggressive bone lesions of osteosarcoma. ACVS's nuance on cruciate disease is worth knowing before agreeing to films: radiographs are only required if surgery is being performed, for surgical planning, though they may support the exam in difficult cases.

Joint fluid analysis (arthrocentesis)

The test that separates a mechanical problem from an inflammatory or infectious one. Merck: fluid should be submitted for both analysis and culture, and analysis identifies abnormal cell numbers or types within the joint.

Blood work and tick-borne disease testing

For shifting or multi-limb lameness with systemic signs, and before any dog goes onto long-term anti-inflammatories. ACVS notes that before surgery or dispensing certain medications, knowing the dog's overall health matters.

Advanced imaging or referral

Cornell: very subtle lameness may need force plate analysis, typically available only at specialty or referral hospitals, and CT or MRI may be recommended. Merck adds diagnostic arthroscopy for direct evaluation of articular surfaces with the option of taking samples.

Bone biopsy

For a suspicious bone lesion. It is the step that decides between an amputation-and-chemotherapy conversation and a fungal or infectious one, and it is not a step to skip on the strength of a radiograph. What it costs

How limping in dogs (lameness) is treated

Rest, pain control and weight management

Cornell's list for lameness of any cause begins with pain control and non-steroidal anti-inflammatories, rest and activity restriction, and weight management. ACVS's version for a cruciate dog managed without surgery is blunt: pain medication improves comfort but the knee still hurts because it is still unstable, so strict leash-based activity restriction is usually the most effective single measure. What rest, pain control and weight management costs

Physical rehabilitation

Cornell lists physical rehabilitation among treatments and ACVS reports that studies show rehabilitation can speed recovery and improve final outcomes regardless of which cruciate surgery is chosen, starting immediately after surgery with passive range of motion, balance work and controlled leash walks. In partial cruciate tears it may delay surgery rather than replace it.

Emergency assessment for trauma or a non-weight-bearing limb

For the hit-by-car dog, the open fracture, the acutely paralysed dog and the hot swollen joint with a fever. The visit exists to separate the limb that needs rest from the one that needs an operating table tonight. What emergency assessment for trauma or a non-weight-bearing limb costs

Cruciate surgery

ACVS: surgical treatment is typically the best treatment because it is the only way to permanently control the instability. Osteotomy techniques (TPLO, TTA, CBLO) cut and reshape the tibia; suture techniques (extracapsular lateral suture, TightRope) stabilise from outside the joint and are often less costly but may not suit larger or younger dogs because of the arthritis that follows. What cruciate surgery costs

Tibial plateau levelling osteotomy specifically

The technique many surgeons prefer for large active dogs. ACVS: a semicircular cut around the top of the shin bone, rotated to a predetermined position and held with a bone plate and screws, with consistent outcomes and a return to an active lifestyle for the majority - at the cost of several weeks of confinement while the bone heals. What tibial plateau levelling osteotomy specifically costs

Surgery for hip dysplasia and patellar luxation

Where the diagnosis turns out to be developmental rather than degenerative. Both have their own price records because both are planned procedures with a wide range of options rather than a single operation. What surgery for hip dysplasia and patellar luxation costs

Patellar luxation surgery

For a kneecap that slips out of its groove badly enough to cause persistent lameness or to be driving arthritis. Merck covers grading and the surgical decision. What patellar luxation surgery costs

Fracture repair

Pins, plates, screws or an external fixator, depending on the bone and the break. This is the branch where a single afternoon changes the bill by an order of magnitude. What fracture repair costs

Amputation for a bone tumour

The standard treatment for appendicular osteosarcoma, usually followed by chemotherapy. It is on this list because a persistent limp in an older large-breed dog is how that diagnosis nearly always starts. What amputation for a bone tumour costs

Outlook and prevention

Cornell's summary is that early diagnosis improves comfort and long-term outcomes, and it is true across most of this list. For cruciate disease, ACVS reports significant improvement in 85-90% of cases after surgical repair, with arthritis progressing more slowly than under medical management. The figure owners are rarely given up front is the other one: ACVS reports that 40-60% of dogs with cruciate disease in one knee will develop it in the other, and that up to 50% do so within the first 12 to 18 months after diagnosis. Budgeting for one knee and getting two is the single most common financial surprise in canine orthopaedics. Osteoarthritis has no cure and is managed; Cornell's point is that the earlier it is diagnosed and managed the better the long-term outcome. Septic arthritis and immune-mediated polyarthritis do well when treated for what they are and badly when treated as a sprain. Osteosarcoma is the one where the prognosis is driven by how early the limp was investigated.

Keep the dog lean. It is the intervention with the best evidence behind it: in a lifetime paired-feeding study of 48 Labradors, dogs fed 25% less than their pair-mates had a significantly longer median lifespan and a later onset of chronic disease, and the hip-joint arm of the same cohort found the median age at first radiographic evidence of hip osteoarthritis was 6 years in the control-fed dogs and 12 years in the restricted-fed ones. ACVS names poor body condition and excess weight as risk factors for cruciate disease that owners can directly influence, through consistent conditioning and controlled food intake. Beyond weight: build fitness gradually rather than doing nothing all week and a five-mile hike on Sunday, keep nails short, check paws and pads after walks, use non-slip runners on hard floors and a ramp into the car for an arthritic dog, and get any limp lasting more than a day or two looked at rather than resting it repeatedly.

What treating limping in dogs (lameness) costs

Costs for limping in dogs (lameness) run from $56 for routine vet checkup (wellness exam) to $10,000 for dog ACL (cranial cruciate ligament) surgery. Which of the 9 procedures below your animal needs is what decides where you land.

Each block below is one procedure we price in full: the national range, the region-by-region table behind it, and how every row was sourced. Rows marked published come from a real price for that geography; rows marked indexed are the national range scaled by a cited regional cost index, and we label them rather than blending the two.

What the invoice for dog ACL (cranial cruciate ligament) surgery looks like

Dog ACL (Cranial Cruciate Ligament) Surgery is the largest single bill on this page, so this is the one worth reading line by line. Clinics quote a bundled number and itemize afterwards; this is the decomposition.

Does pet insurance cover limping in dogs (lameness)?

Dog ACL (Cranial Cruciate Ligament) Surgery is normally covered by a standard accident-and-illness policy. Cruciate surgery is one of the most frequently claimed conditions on accident-and-illness policies and is normally covered once any waiting period has passed. Two traps matter more here than on any other procedure. First, if one knee was already diagnosed before enrolment, MetLife confirms a claim on the second knee is typically excluded as pre-existing - and the contralateral rupture rate is 40-60%. Second, several carriers apply a longer waiting period specifically to cruciate conditions; that practice is widely described but we could not verify the exact length against any carrier's own published policy document, so check the wording before relying on it.

What you would get back: 70-90% of the covered bill after the annual deductible, on a policy bought before any lameness was recorded in either knee.

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 limping in dogs (lameness) — 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–$10,000 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 ACL (cranial cruciate ligament) surgery shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.

Common questions

Related conditions and costs

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.

• dog biopsy cost $144–$1,110 — Taking a tissue sample from a dog and having a pathologist read it, priced from the laboratory fee upward rather than from a quote downward.

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.
• 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.
• 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.
• 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.
• 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 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.
• 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 ear infection treatment — Inflammation of the ear canal, almost always with a yeast or bacterial overgrowth on top of it.
• 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 skin allergies — A lifelong immune reaction to ordinary environmental substances - pollens, moulds, dust mites, dander - that shows up as itching rather than sneezing.
• dog UTI symptoms — A bacterial infection of the bladder, usually Escherichia coli travelling up the urethra from the perineum.

• 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.
• 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.
• 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.
• 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.
• 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.
• yeast infection in dogs — Malassezia pachydermatis is a yeast that lives on normal dog skin and in normal ears.
• 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.
• worms in dogs — Four different worms with four different stories, grouped together only because they all live in a dog's gut.
• 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.
