Dog Coughing: How to Tell Which of Eight Causes It Is

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. This is an emergency and needs a vet now if any of these are true: Laboured breathing at rest, or breathing with the mouth open when the dog is not hot or excited; Blue or grey gums, tongue or muzzle.

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.
   • Laboured breathing at rest, or breathing with the mouth open when the dog is not hot or excited
   • Blue or grey gums, tongue or muzzle
   • Contracting the belly to breathe, or standing with head and neck stretched out to get air
   • Fainting or collapsing during or after a coughing fit
   • Coughing up pink froth, or a rapid deterioration over hours

   Cornell's respiratory distress list is exactly this: rapid open-mouth breathing, a bluish tinge to the gums and muzzle, abdominal effort, an extended head and neck, increased breathing noise, weakness or collapse - and the instruction is to go quickly and calmly to the nearest emergency hospital, calling ahead. Keep the car cool, because heat drives panting and panting makes it worse. Cornell also says plainly that if you are not sure whether your dog is in respiratory distress, seek help anyway.

2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
   • Coughing with a fever, refusing food, or obvious lethargy
   • A wet, productive cough with nasal discharge
   • A cough that is clearly worse rather than better after the first five days
   • A puppy, an elderly dog, or a dog with known heart or lung disease that starts coughing
   • Coughing that begins or worsens at night, or after lying down

   This cluster separates pneumonia and heart disease from an ordinary infectious cough. Merck's pneumonia signs are coughing, fever, lethargy, anorexia and respiratory distress, with the cough either dry or wet and productive, and the treatment involving oxygen supplementation if the dog is hypoxaemic. A cough that starts at night or when the dog lies down, particularly in an older small-breed dog with a known murmur, is the classic pattern for heart disease and is not something to watch for a week.

3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
   • A dry, honking cough in a bright, eating dog after boarding, grooming or daycare
   • A goose-honk cough in a small breed, triggered by excitement or by pulling on the collar
   • Any cough that has gone on for more than a week
   • Coughing with exercise intolerance or a recent drop in stamina
   • Coughing in a dog that is not on year-round heartworm prevention

   Book an appointment, and keep an infectious-looking dog away from other dogs while you wait. ACVS describes the tracheal collapse cough as harsh, dry and goose-honking, brought on by picking the dog up or by pressure on the collar, and lists Yorkshire Terriers, Pomeranians, Poodles and Chihuahuas as the classic breeds. Heartworm belongs on this rung too: the American Heartworm Society states that many dogs show few or no symptoms in the early stages and that the signs, when they appear, may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite and weight loss. It is diagnosed on a blood test, not on how the cough sounds.

4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
   • A dry honking cough in the first few days after a known kennel-cough exposure, in a dog that is bright, eating and breathing normally
   • An occasional single cough after drinking, eating fast, or pulling against a collar
   • A recovering dog whose cough is fading in the second week

   Merck's expected course for infectious tracheobronchitis is that severity diminishes during the first five days even though the cough itself persists for 10 to 20 days, and that dogs with a cough only often do not need hospitalisation. Count the resting breathing rate once or twice a day while the dog is asleep or settled - Cornell's normal range is 12 to 30 breaths a minute, and a rate that climbs and stays up is the signal to stop monitoring and book.

A cough is a sign, not a diagnosis. The same dry hack comes from an infection that clears itself in a fortnight and from a heart valve that is failing, and no article can tell those apart by describing the noise.

Count the breathing, not the coughing

The useful measurement is what the dog's breathing does between coughs. Cornell puts a normal resting respiratory rate at 12 to 30 breaths a minute — count for thirty seconds while the dog is asleep or settled, and double it.

A dog that is working to breathe at rest is an emergency regardless of what is causing the cough. Cornell's distress list is specific: rapid open-mouth breathing when the dog is not hot or excited, a bluish tinge to the gums and muzzle, using the belly to breathe, standing with head and neck stretched out, increased noise, weakness or collapse.

The instruction that comes with it is to go quickly and calmly to the nearest emergency hospital and call ahead. Keep the car cool: heat drives panting, and panting makes every airway problem on this page worse.

Cornell adds the sentence that matters most for an owner at 2am — if you are not sure whether your dog is in respiratory distress, seek help anyway.

Two weeks, not two days

The commonest cause of a dog cough runs longer than most owners expect. Merck's course for infectious tracheobronchitis is that severity diminishes during the first five days while the illness itself persists for 10 to 20 days.

So a dog that looks better on day three is still infectious. The isolation window is the full 10 to 20 days, not the two days it takes to stop looking ill, and that is the single most useful thing to know if your dog picked this up at daycare and lives near other dogs.

Antibiotics are usually not part of it. Merck states they are generally not needed for kennel cough unless there is evidence of pneumonia, and that dogs with a cough only often do not require hospitalisation. Kennel cough has its own page in this library, which covers the Bordetella vaccine and the incubation period in detail.

What changes that assessment is fever, refusing food, obvious lethargy, or a cough that is clearly worse rather than better after the first five days. Merck's pneumonia picture is coughing with fever, lethargy, anorexia and respiratory distress — a different appointment, and a same-day one.

The honk in a small dog is a different disease

A harsh, dry, goose-honking cough set off by excitement, by picking the dog up or by pressure on the collar is tracheal collapse, not an infection. ACVS describes it as a chronic, progressive, irreversible weakening of the C-shaped cartilage rings of the windpipe, and names Yorkshire Terriers, Pomeranians, Poodles and Chihuahuas as the classic breeds.

ACVS grades it from 1, at 25% collapse, to 4, at 100%. That grading matters because the treatment path splits on it: ACVS reports medical management — weight loss, medication to reduce airway spasm and inflammation, and sedation to break the cough-irritation-cough cycle — works for up to 70% of dogs, particularly those with mild collapse.

Dogs that progress need surgical rings or an intraluminal stent, and ACVS is clear that medical management continues for life afterwards regardless. This is managed, never cured.

Three changes cost nothing and are supported directly by ACVS. Walk the dog on a harness rather than a collar. Keep it lean, because ACVS names being overweight among the factors in showing signs. And keep it away from smoke — ACVS notes coughing can be stimulated by smoke carried in on clothing and hair, not only by smoking in the room.

Plain radiographs do not always show it, either. ACVS notes fluoroscopy — a moving x-ray that shows the trachea through the breathing cycle — is what demonstrates a collapse that changes with each breath.

A cough that starts at night in an older small dog

Coughing that begins or worsens at night, or after the dog lies down, particularly in an older small-breed dog with a known murmur, is the classic heart-disease pattern. It is not something to watch for a week.

Myxomatous mitral valve disease is the commonest acquired heart disease of dogs, and the ACVIM cardiology panel revised its consensus guidelines in 2019, noting that management before the onset of clinical signs of heart failure has changed substantially since 2009.

For an owner that translates into one instruction: a murmur found at a routine examination is now something to stage rather than something to wait on. The useful window is before the coughing starts.

Small breeds complicate this in a way worth naming. ACVS points out that small-breed dogs frequently have both a collapsing trachea and a mitral murmur — so an echocardiogram and an airway assessment answer different questions, and treating the wrong one wastes months.

Does a coughing dog need a heartworm test?

Yes, and it is one of the cheapest tests in the building. The American Heartworm Society lists a mild persistent cough among the signs, alongside reluctance to exercise, fatigue after moderate activity, decreased appetite and weight loss.

The reason to test rather than to reason from symptoms is in the same source: many dogs show few or no symptoms in the early stages. A blood antigen test answers it; how the cough sounds does not.

The severe end is worth knowing about because it is sudden. A heavy worm burden can cause caval syndrome — cardiovascular collapse with laboured breathing, pale gums and dark, coffee-coloured urine — which few dogs survive without surgical removal of the blockage.

The economics are stark and they are in the cost section below. A monthly preventive is one of the smallest recurring costs in dog ownership; heartworm treatment is a staged, months-long protocol with strict exercise restriction and a four-figure ceiling. Cats get the same disease with a different disguise, which is covered on our page about coughing in cats.

The coughs that are not infections at all

Three presentations get treated as kennel cough and are not.

Aspiration pneumonia follows persistent vomiting, megaoesophagus, or medication or food given improperly into the mouth. A dog that has recently been vomiting or had an anaesthetic and now coughs is a different problem from a dog that has been to daycare, and Merck's treatment for it involves oxygen supplementation where the dog is hypoxaemic, which is hospital care rather than home care.

An inhaled grass awn produces a sudden, violent cough in a dog that was completely fine an hour earlier, usually after a walk in long grass. The history is the diagnosis.

Laryngeal paralysis and brachycephalic airway syndrome produce noisy breathing and a changed bark more than a true cough, and both get dramatically worse in heat and excitement. That is why a cough in a Labrador in July and a cough in a Yorkshire Terrier in December are not the same investigation.

And in an older dog, a chronic cough that has not resolved earns a chest radiograph rather than a second course of antibiotics, because airway and lung tumours sit at the end of this differential list.

What each answer costs

The consultation is where this page's value is realised, because the cheap answer and the expensive answer sound identical from the sofa. An examination with chest auscultation separates crackles from a murmur from an upper-airway noise, and a tracheal pinch that reproduces the cough points at the airway rather than the lungs.

Be aware of what we do not price. Thoracic radiographs are the single most useful test in a coughing dog and we do not yet publish a researched price record for them, so they are not in the figures below. Neither are fluoroscopy, airway endoscopy or echocardiography. We would rather name the gap than fill it with an estimate.

What we do price is the four ends of this problem: the routine consultation, the emergency visit for the dog in respiratory distress, the Bordetella vaccine that reduces the severity of the commonest cause, and heartworm treatment — the outcome that year-round prevention exists to avoid. Read those four together and the shape of the decision is obvious: the two preventive lines are the smallest numbers on the page, and the two reactive ones are the largest.

Why coughing in dogs happens

Canine infectious respiratory disease complex (kennel cough)

Merck lists Bordetella bronchiseptica, canine parainfluenza virus, canine adenovirus 2, canine influenza and, less likely, distemper. This is what most people mean by a dog cold. It is usually mild and self-limiting, and Merck states that antibiotics are usually not needed unless there is evidence of pneumonia.

Pneumonia, including aspiration pneumonia

Merck: inflammation of the lung tissue from bacteria, viruses, fungi, parasites or protozoa, or from aspirating stomach contents. Aspiration pneumonia follows persistent vomiting, megaoesophagus, or improperly administered medication or force-feeding - which is why a coughing dog that has recently been vomiting or had an anaesthetic is a different problem from a coughing dog that has been to daycare.

Tracheal collapse

ACVS: a chronic, progressive, irreversible weakening of the C-shaped cartilage rings of the windpipe, which flatten until the airway collapses, sometimes extending into the mainstem bronchi. It is graded 1 (25% collapse) to 4 (100%), affects small breeds, and ACVS notes overweight dogs and dogs living with smokers may be more likely to show signs.

Heart disease

Myxomatous mitral valve disease is the commonest acquired heart disease of dogs and its consensus guidelines were revised by an ACVIM cardiology panel in 2019, which notes that management before the onset of clinical signs of heart failure has changed substantially since 2009. That is the practical point for an owner: a murmur found on a routine exam is now something to stage rather than something to wait on.

Heartworm disease

Merck covers Dirofilaria immitis infection in dogs, cats and ferrets. The American Heartworm Society lists a mild persistent cough among the signs, alongside reluctance to exercise, fatigue after moderate activity, decreased appetite and weight loss - while warning that many dogs show few or no symptoms early on, and that a heavy worm burden can cause caval syndrome, a sudden cardiovascular collapse marked by laboured breathing, pale gums and dark, coffee-coloured urine, which few dogs survive without surgical removal of the blockage. It is mosquito-borne, preventable, and the treatment when it is found is one of the more expensive things on this site.

Airway parasites and foreign bodies

Merck lists lung nematodes, lung flukes and parasitic bronchial invasion among the causes of pneumonia and respiratory disease in small animals. A grass awn inhaled on a walk produces a sudden, violent, one-sided cough in a dog that was fine an hour earlier.

Laryngeal paralysis and brachycephalic airway syndrome

Cornell lists both among the causes of respiratory distress. These produce noisy breathing and a change in the bark as much as a cough, they get dramatically worse in heat and excitement, and they are the reason a cough in a Labrador in July and a cough in a Yorkshire Terrier in December are not the same investigation.

Airway and lung tumours

Merck includes neoplasia of the respiratory system among the differentials. It is uncommon relative to the rest of this list, but it is the reason a chronic cough in an older dog gets a chest radiograph rather than a second course of antibiotics.

How a vet diagnoses coughing 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.

Physical examination with chest auscultation

Listening to the chest separates crackles and consolidation from a murmur from an upper-airway noise, and a tracheal pinch that reproduces the cough points at the airway rather than the lungs. Merck notes auscultation in pneumonia may reveal crackles or dull areas where lung is consolidated. What it costs

Thoracic radiographs

The single most useful test in a coughing dog. Merck: thoracic radiographs may show interstitial or alveolar changes in pneumonia. ACVS notes chest radiographs help in some tracheal collapse cases and are useful for ruling other things out and assessing heart size - but that tracheal collapse is not always visible on plain films.

Heartworm antigen test

A blood test that costs a fraction of a chest radiograph and rules out a diagnosis whose treatment is one of the more expensive on this site. The American Heartworm Society publishes the current canine guidelines for diagnosis, prevention and management.

Fluoroscopy or airway endoscopy

For suspected tracheal collapse. ACVS: fluoroscopy is a moving x-ray that shows the trachea through the breathing cycle, which matters because the airway diameter changes between inspiration and expiration; endoscopy gives the best view of the airway lining and allows fluid samples for culture and analysis.

Airway wash for cytology and culture

Merck's position for pneumonia is that bacterial culture and sensitivity testing is required and empirical antimicrobials should be changed based on bronchoalveolar lavage results, with anaerobe and mycoplasma culture considered in refractory cases.

Echocardiogram

Assesses cardiac function and stages heart disease. ACVS lists it among the tests for a tracheal collapse work-up as well, because small-breed dogs frequently have both a collapsing trachea and a mitral murmur, and treating the wrong one wastes months.

How coughing in dogs is treated

Rest and supportive care at home

The correct treatment for most infectious coughs. Merck: dogs with a cough only often do not require hospitalisation, and the disease is often self-limiting, with severity diminishing during the first five days while the illness persists for 10 to 20 days. Keep the dog away from other dogs for that whole window.

Examination to identify the cause

The visit that decides which of the eight causes above this is. It is worth paying for precisely because the cheap answer and the expensive answer sound the same from the sofa. What examination to identify the cause costs

Antibiotics only where there is evidence of pneumonia

Merck: antibiotics are usually not needed for kennel cough unless there is evidence of pneumonia. Where they are needed, Merck's pneumonia guidance is to start empirically, reassess if there is no response in 48 to 72 hours, and continue for a week after clinical and radiographic signs have resolved.

Oxygen and hospitalisation for respiratory distress or pneumonia

Merck: oxygen therapy in a cage or by nasal catheter at 40-60% if the dog is hypoxaemic, plus nebulisation and coupage, bronchodilators, and treatment of shock where present. This is the rung the emergency signs above lead to. What oxygen and hospitalisation for respiratory distress or pneumonia costs

Medical management of tracheal collapse

ACVS: weight loss, medication to reduce airway spasm and inflammation, and sedation to break the cough-irritation-cough cycle, plus keeping the dog away from smoke and airborne irritants. ACVS reports medical management works for up to 70% of dogs, particularly those with mild collapse, and that it has to continue for life even if surgery or a stent follows.

Heartworm treatment

Where the antigen test is positive. It is a staged, months-long protocol with strict exercise restriction, and it is the reason the monthly preventive is the cheapest decision on this page by a wide margin. What heartworm treatment costs

Bordetella vaccination

Prevention rather than treatment. Merck describes an intranasal live avirulent Bordetella vaccine, often combined with parainfluenza, alongside the core distemper, parainfluenza and adenovirus-2 series. It is a lifestyle vaccine for dogs that board, are groomed or use parks, and like a human flu shot it reduces severity rather than guaranteeing the dog will not catch anything. What bordetella vaccination costs

Outlook and prevention

This depends entirely on which cause it turns out to be, which is the reason the page exists. An infectious cough in a healthy adult dog resolves in about two weeks with no treatment at all. Pneumonia is survivable but needs monitoring - Merck recommends repeating chest radiographs every two weeks or sooner until the changes resolve. Tracheal collapse is described by ACVS as chronic, progressive and irreversible: medical management controls up to 70% of cases, mostly the mild ones, and dogs that progress need surgical rings or an intraluminal stent, with medical management continuing for life afterwards regardless. Heart disease is managed rather than cured, and the ACVIM consensus panel's point is that the useful window is before congestive signs appear. Heartworm is curable and the treatment is expensive and slow.

Vaccinate the dogs whose lifestyle calls for it and keep a coughing dog home for the full 10-to-20-day window rather than the two days it takes to look better. Keep heartworm prevention going year-round - it is a monthly cost against a four-figure treatment. Walk small breeds on a harness rather than a collar, because ACVS lists pressure on the collar as a trigger for the tracheal collapse cough. Keep dogs lean; ACVS names being overweight as a factor in showing signs of tracheal collapse, and it makes every airway problem on this list worse. Do not smoke around a dog with an airway disease - ACVS notes coughing can be stimulated by smoke carried in on clothing and hair. And get a heart murmur staged when it is found rather than when the dog starts coughing at night.

What treating coughing in dogs costs

Costs for coughing in dogs run from $15 for bordetella (kennel cough) vaccine to $1,800 for dog heartworm treatment. Which of the 4 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 heartworm treatment looks like

Dog Heartworm Treatment 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 coughing in dogs?

Dog Heartworm Treatment is normally covered by a standard accident-and-illness policy. Heartworm treatment is covered by an accident-and-illness policy where the infection was not present before enrolment or during the waiting period - but a positive test at the adoption or enrolment examination excludes it, and that is when most dogs are tested. Prevention is not covered by an accident-and-illness policy at all; it belongs to a wellness add-on where one is offered. Carriers can also decline or restrict cover on a dog with a heartworm history, so the cheap outcome here is not the cheap treatment, it is never needing one.

What you would get back: 70-90% of the covered bill after the deductible, where the infection was acquired after the waiting period ended. A dog that tested positive before enrolment gets nothing.

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 coughing 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 $15–$1,800 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 heartworm treatment 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.
• 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 heartworm treatment cost $300–$1,800 — Killing adult heartworms in a dog with a course of melarsomine injections, plus the two months of drugs, imaging and exercise restriction that go around them.
• bordetella (kennel cough) vaccine cost $15–$56 — The kennel cough vaccine, sold intranasally, orally or by injection, required by most boarding and grooming facilities rather than by law, and priced per dose from $15 to $56.

Related conditions

• 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 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 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 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.
• 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.
• worms in dogs — Four different worms with four different stories, grouped together only because they all live in a dog's gut.
• 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.
• 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.
• 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.
• 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.
• 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.
