Urinary Blockage in Cats: FLUTD, the Hours You Have, and Costs
A group of conditions causing painful, frequent, bloody or unproductive urination in cats. This is an emergency and needs a vet now if any of these are true: Straining in the litter box and producing little or no urine; Crying out in the box, or repeatedly going in and out of it.
Is this an emergency?
Worst first. Find the highest rung that matches what you can actually see, and act on that one — not on the one you hope applies.
- Emergency — go nowGo to an emergency vet or the nearest open clinic now. Do not wait for morning.
- Straining in the litter box and producing little or no urine
- Crying out in the box, or repeatedly going in and out of it
- A male cat that is increasingly distressed, restless or hiding
- Vomiting, collapse, or lying still with a hard, painful belly
- Licking the genital area constantly with nothing coming out
Cornell: urethral obstruction is a true medical emergency, and the time from complete obstruction until death may be less than twenty-four to forty-eight hours. Do not wait for morning, do not wait to see if he settles. A blocked cat cannot excrete potassium, and the resulting electrolyte derangement stops the heart before the bladder ruptures. Male and neutered male cats are at far greater risk because the urethra is longer and narrower.
- Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
- Visible blood in the urine
- Urinating outside the litter box in a cat that never does
- Frequent small puddles with obvious discomfort
- A female cat straining but still producing urine
- Any of the above in a cat with a history of blockage
These are the classic signs Merck lists - haematuria, pollakiuria, stranguria and periuria - and in a male cat they are the rung immediately above obstruction. A cat that is still passing urine today can be blocked tonight, so 'still peeing' is a reason to be seen today, not a reason to wait.
- Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
- A recurring pattern of mild straining that resolves in a day or two
- House soiling with no straining and no blood
- A previously diagnosed FIC cat between episodes
Book an appointment. Recurrence is the norm with idiopathic cystitis, and the useful work at this rung is on stress, water intake and litter box management rather than another course of antibiotics.
- Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
- An indoor, overweight, middle-aged male cat with no urinary signs
- A multi-cat household where a resident cat has had episodes before
Cornell describes the risk profile precisely: middle-aged, overweight cats that get little exercise, use an indoor litter box, have restricted outdoor access and drink less water, with males at increased risk and household stress as a contributing factor. Every item on that list is modifiable.

A male cat that cannot pass urine dies of a heart-rhythm problem, not a burst bladder. He cannot excrete potassium, the level climbs, and Cornell puts the time from complete obstruction to death at less than twenty-four to forty-eight hours.
"Cat UTI" is usually the wrong name
Most cats with these signs do not have an infection. Both Cornell and Merck give feline idiopathic cystitis as the commonest diagnosis in cats with lower urinary tract signs, and idiopathic means the cause is unknown.
That matters because the wrong name leads to the wrong treatment. A cat put on antibiotics for a bladder that has no bacteria in it gets a fortnight of tablets, a self-limiting episode that would have settled anyway, and a household convinced the antibiotics worked. The next episode gets the same treatment.
A urine culture is what settles it. Bacterial infection is real — more likely in older cats and cats with other disease — but it is much less common than the phrase "cat UTI" implies, and the culture is what decides whether antibiotics have any role at all.
Merck frames idiopathic cystitis as an interplay between the bladder, the nervous system and the stress response. It is a pain condition, which is why analgesia rather than antibiotics is the mainstay of treatment.
The window is hours, and male cats have the narrow one
Male and neutered male cats block because the urethra is longer and narrower, not because they get more urinary disease than females. The same amount of debris that a female passes will stop a male.
The emergency signs are behavioural before they are medical: repeated trips in and out of the tray, straining with nothing produced, crying in the box, constant licking at the genitals. Owners routinely read this as constipation, which is the single most expensive misreading in feline medicine.
A female cat straining but still producing urine is the rung below — seen today, not tonight. The same signs in a male cat are seen tonight, because "he is still passing a little" is a description of a partial obstruction.
There is one thing worth doing on the way. Note the time you last saw the cat produce urine, and say it at the door — a cat that has been blocked since yesterday morning is a different case from one that started straining an hour ago, and the potassium is what makes it different. It changes how fast he is stabilised before anaesthesia and it is information nobody in the building has except you.
The noise version of this emergency is covered on our page on excessive meowing in cats, because a crying cat at the litter tray is one of the commonest ways this presents to an owner who has not yet thought about urine at all.
Nearly a third of unblocked cats block again
This is the number that should decide what happens after the emergency, and almost nobody publishes it. In a VetCompass study of 237,825 male cats under UK primary veterinary care, 29.6% of catheterised cats required repeat catheterisation — from 854 cases with follow-up data.
The same cohort gives the incidence: a 0.54% one-year risk of urethral obstruction in male cats (95% CI 0.51–0.57), from 1,293 cases. It is UK primary-care data rather than US, and it is quoted here because it is the only figure in this area with a real denominator behind it.
Put the 29.6% next to the prices below and the decision changes shape. An emergency unblocking is not one bill; for roughly one cat in three it is the first of at least two, at emergency rates, at whatever hour it happens. Perineal urethrostomy — removing the narrow section of urethra and creating a wider opening — is a planned operation at a planned price, and it is the thing that ends the cycle.
That is not an argument that every unblocked cat should have surgery. It is an argument that the question belongs in the conversation on day one rather than after the third emergency visit, and that the cost of perineal urethrostomy in cats should be read against a 30% chance of repeating the emergency rather than against zero.
Do urinary diets work?
Less than the marketing claims, and Cornell's wording is precise about the difference. Urinary diets may reduce the likelihood that a cat with idiopathic cystitis obstructs — and Cornell states there is no evidence they reduce the incidence of lower urinary tract signs themselves.
Read that as two separate claims. Fewer blockages is a serious benefit and worth paying for in a cat that has blocked before. Fewer episodes of painful, bloody urination is not something the evidence supports, so a cat that keeps having episodes on a urinary diet is not failing the diet.
Stones are the exception where diet does real work. Cornell notes struvite stones may be dissolved with a prescription diet, with surgery if that fails. Calcium oxalate stones cannot be dissolved at all and often have to come out surgically, and their share of cases has risen as commercial diets have driven struvite down.
A clear x-ray does not clear the cat
Urethral plugs do not show on radiographs. Cornell describes a plug as soft, compressible material containing variable amounts of minerals, cells and mucus-like protein — a leading cause of obstruction, and not the same thing as a stone.
So "the x-ray was clear" answers the stone question and not the blockage question. What answers the blockage question is a physical examination: a large, firm, painful bladder in a straining cat means obstruction, and that cat is treated immediately rather than worked up.
Ultrasound earns its place afterwards rather than at the door. It shows bladder wall thickening, sediment, and the stones radiographs miss, which is why it appears in the cost section below as a diagnostic rather than an emergency line.
What actually reduces episodes
Water, litter boxes and stress, in that order. Merck's management list is environmental enrichment, increasing water intake including a move to canned food, pheromones and analgesia — and Cornell reports that environmental enrichment reduces the severity and frequency of episodes.
Practically: more water bowls than you think are needed, moving water, wet food where the cat will take it. One more litter box than you have cats, cleaned daily, in quiet places rather than beside the washing machine. Stable routines, because Cornell names change in the household, in feeding and in the number of animals as triggers.
Cornell's risk profile is worth checking your own cat against: middle-aged, overweight, little exercise, indoor litter box, restricted outdoor access, low water intake, male. Every item on that list is modifiable, which is unusual on this site.
What each branch of this costs
The bill divides cleanly and the branches are far apart. The examination that finds a full bladder is the cheapest line here. The emergency visit that unblocks him, with sedation, catheterisation, fluids and correction of the potassium, is the one that happens at 2am. Imaging sits in the middle. And perineal urethrostomy is the largest single figure on the page.
One gap is worth stating plainly: we do not publish a researched price record for feline cystotomy, the operation that removes stones, so it is described on this page and not priced. We would rather leave a hole than fill it with a number we cannot source.
The figures below are national ranges with the regional tables behind them. Read them with the 29.6% in mind — for a male cat that has blocked once, the honest budget is not one emergency.
Why feline lower urinary tract disease (FLUTD) and urinary blockage happens
- Feline idiopathic cystitis
- The most common diagnosis in cats with lower urinary tract signs, per both Merck and Cornell, and idiopathic means the cause is unknown. Merck describes an interplay between the bladder, the nervous system and the stress response. Cornell notes stress appears to be an important factor and that environmental enrichment reduces the severity and frequency of episodes.
- Urethral plugs
- Cornell: a soft, compressible material containing variable amounts of minerals, cells and mucus-like protein. Plugs are a leading cause of obstruction and are not the same thing as stones, which is why an x-ray showing no stone does not rule out a blockage.
- Bladder stones
- Cornell names struvite and calcium oxalate as the two commonest types. Struvite are becoming less common as commercial diets limit magnesium and acidify urine, while the calcium oxalate share has risen - and unlike struvite, oxalate stones cannot be dissolved by diet and often have to come out surgically.
- Bacterial urinary tract infection
- Real, but much less common than the name 'cat UTI' implies, and more likely in older cats and cats with other disease. This is the practical reason a urine culture matters: it decides whether antibiotics have any role at all.
- Anatomy and sex
- Cornell: male and neutered male cats are at greater risk of obstruction because the urethra is longer and narrower. It is not that males get more urinary disease - it is that the same amount of debris blocks them and not females.
- Stress and environment
- Environmental change, a change in feeding routine, a change in the number of animals in the household. Cornell lists these directly as sources of stress that can trigger idiopathic cystitis episodes.
How a vet diagnoses feline lower urinary tract disease (FLUTD) and urinary blockage
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 and bladder palpation
- The fastest and most important test in the building: a large, firm, painful bladder in a straining cat means obstruction and the cat is treated immediately rather than worked up. What it costs
- Urinalysis
- Crystals, blood, pH, concentration and evidence of infection. The single test that separates idiopathic cystitis from stones from an actual infection.
- Urine culture and sensitivity
- Confirms whether bacteria are actually present before a cat is put on antibiotics for a condition that usually does not involve them.
- Blood work and electrolytes
- In a blocked cat this is the emergency test: potassium and kidney values decide how sick he is and how fast he has to be stabilised before anaesthesia.
- Radiographs and abdominal ultrasound
- Cornell notes x-rays or ultrasound are usually used to diagnose uroliths. Ultrasound also shows bladder wall thickening, sediment and the stones that x-rays miss. What it costs
How feline lower urinary tract disease (FLUTD) and urinary blockage is treated
- Emergency unblocking and hospitalisation
- A urinary catheter passed under sedation, the bladder emptied and flushed, intravenous fluids and correction of the electrolyte derangement, then the catheter left in place while the cat stabilises. This is the treatment that saves the blocked cat's life and it is the one that has to happen tonight. What emergency unblocking and hospitalisation costs
- Pain relief and supportive care for idiopathic cystitis
- Merck gives transmucosal buprenorphine at 0.01-0.03 mg/kg in the cheek pouch every 8-12 hours as needed. FIC is a pain condition, and analgesia rather than antibiotics is the mainstay. What pain relief and supportive care for idiopathic cystitis costs
- Environmental modification and increased water intake
- Merck's management list includes environmental enrichment, increasing water intake (including a move to canned food), pheromones and analgesia. Cornell adds that cats should be given a safe, clean place to urinate and opportunities to express natural predatory behaviour, and that routines should stay consistent.
- Diet for stone dissolution or prevention
- Cornell: struvite stones may be dissolved with a prescription diet, and surgery follows if that fails. But the same source is careful about urinary diets in general - they may reduce the likelihood that an FIC cat obstructs, while there is no evidence they reduce the incidence of lower urinary tract signs themselves.
- Surgical stone removal
- Cornell: surgical removal is often required for stones that will not dissolve or pass, and cats that have formed uroliths are at increased risk of forming them again. We do not publish a price record for feline cystotomy, so this line has no cost join on this page.
- Perineal urethrostomy
- For the cat that keeps re-blocking: the narrow penile section of the urethra is removed and a wider opening created. It is the operation that ends the cycle of emergency visits, and it is the single largest line in this condition's cost. What perineal urethrostomy costs
Outlook and prevention
A cat unblocked promptly usually recovers well, but re-obstruction is common: in the UK primary-care study below, 29.6% of catheterised cats needed repeat catheterisation. Idiopathic cystitis episodes are self-limiting over days to weeks, and Cornell notes that veterinarians treat the condition largely to prevent the signs recurring rather than to cure them, since the underlying cause is unknown. Cats that have formed stones tend to form them again. A cat that reaches obstruction and is not treated dies, and Cornell puts the window at less than twenty-four to forty-eight hours from complete blockage.
Water first: canned food, more bowls, moving water, and a wet-food shift are what Merck actually lists. Then litter boxes - one more than the number of cats, cleaned daily, in quiet places. Then stress: keep routines stable, add vertical space and hiding places, and use pheromones where the household is tense. Keep the cat lean; Cornell's risk profile is a middle-aged, overweight, under-exercised indoor cat. And for a male cat with any history of straining, know the emergency signs, because his margin is measured in hours.
How common it is: 0.54% one-year incidence risk of urethral obstruction (95% CI 0.51-0.57) — 237,825 male cats under UK primary veterinary care in 2016, VetCompass Programme; 1,293 incident cases. Source.

Does pet insurance cover feline lower urinary tract disease (FLUTD) and urinary blockage?
Cat PU Surgery (Perineal Urethrostomy) is normally covered by a standard accident-and-illness policy. Urethral obstruction is an illness and PU surgery is covered by accident-and-illness policies once the waiting period has passed - but the timing is brutal. ACVS notes that obstructive episodes recur in many cats within 6-12 months and that PU is recommended only after multiple occurrences that cannot be unblocked or managed medically. By the time surgery is on the table there are two or three documented blockages in the record, which is exactly what a carrier needs to call the surgery a continuation of a pre-existing condition. The policy has to be in force before the first blockage, not before the surgery. Prescription urinary diets, which are the main thing preventing the next episode, are usually excluded as food. MetLife publishes one worked example at the expensive end: a seven-year-old domestic short-hair hospitalised for a urinary obstruction and then operated on ran a total bill of over $7,000, of which the owners recovered almost $6,200.
What you would get back: 70-90% of the covered bill after the annual deductible, on a policy in force before the first obstruction was recorded.
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 feline lower urinary tract disease (FLUTD) and urinary blockage — 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–$2,395 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 cat PU surgery (perineal urethrostomy) shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.
Common questions
Is feline lower urinary tract disease (FLUTD) and urinary blockage an emergency?
Treat it as an emergency if any of these are true: Straining in the litter box and producing little or no urine; Crying out in the box, or repeatedly going in and out of it; A male cat that is increasingly distressed, restless or hiding; Vomiting, collapse, or lying still with a hard, painful belly; Licking the genital area constantly with nothing coming out. Cornell: urethral obstruction is a true medical emergency, and the time from complete obstruction until death may be less than twenty-four to forty-eight hours. Do not wait for morning, do not wait to see if he settles. A blocked cat cannot excrete potassium, and the resulting electrolyte derangement stops the heart before the bladder ruptures. Male and neutered male cats are at far greater risk because the urethra is longer and narrower.
How much does it cost to treat feline lower urinary tract disease (FLUTD) and urinary blockage?
Costs for feline lower urinary tract disease (FLUTD) and urinary blockage run from $56 for routine vet checkup (wellness exam) to $2,395 for cat PU surgery (perineal urethrostomy). Which of the 4 procedures below your animal needs is what decides where you land.
How is feline lower urinary tract disease (FLUTD) and urinary blockage diagnosed?
Physical examination and bladder palpation: The fastest and most important test in the building: a large, firm, painful bladder in a straining cat means obstruction and the cat is treated immediately rather than worked up. Urinalysis: Crystals, blood, pH, concentration and evidence of infection. The single test that separates idiopathic cystitis from stones from an actual infection. Urine culture and sensitivity: Confirms whether bacteria are actually present before a cat is put on antibiotics for a condition that usually does not involve them. Blood work and electrolytes: In a blocked cat this is the emergency test: potassium and kidney values decide how sick he is and how fast he has to be stabilised before anaesthesia. Radiographs and abdominal ultrasound: Cornell notes x-rays or ultrasound are usually used to diagnose uroliths. Ultrasound also shows bladder wall thickening, sediment and the stones that x-rays miss.
Does pet insurance cover feline lower urinary tract disease (FLUTD) and urinary blockage?
Cat PU Surgery (Perineal Urethrostomy) is normally covered by an accident-and-illness policy taken out before the signs started. Urethral obstruction is an illness and PU surgery is covered by accident-and-illness policies once the waiting period has passed - but the timing is brutal. ACVS notes that obstructive episodes recur in many cats within 6-12 months and that PU is recommended only after multiple occurrences that cannot be unblocked or managed medically. By the time surgery is on the table there are two or three documented blockages in the record, which is exactly what a carrier needs to call the surgery a continuation of a pre-existing condition. The policy has to be in force before the first blockage, not before the surgery. Prescription urinary diets, which are the main thing preventing the next episode, are usually excluded as food. MetLife publishes one worked example at the expensive end: a seven-year-old domestic short-hair hospitalised for a urinary obstruction and then operated on ran a total bill of over $7,000, of which the owners recovered almost $6,200.
What is the outlook for a pet with feline lower urinary tract disease (FLUTD) and urinary blockage?
A cat unblocked promptly usually recovers well, but re-obstruction is common: in the UK primary-care study below, 29.6% of catheterised cats needed repeat catheterisation. Idiopathic cystitis episodes are self-limiting over days to weeks, and Cornell notes that veterinarians treat the condition largely to prevent the signs recurring rather than to cure them, since the underlying cause is unknown. Cats that have formed stones tend to form them again. A cat that reaches obstruction and is not treated dies, and Cornell puts the window at less than twenty-four to forty-eight hours from complete blockage.
Can feline lower urinary tract disease (FLUTD) and urinary blockage be prevented?
Water first: canned food, more bowls, moving water, and a wet-food shift are what Merck actually lists. Then litter boxes - one more than the number of cats, cleaned daily, in quiet places. Then stress: keep routines stable, add vertical space and hiding places, and use pheromones where the household is tense. Keep the cat lean; Cornell's risk profile is a middle-aged, overweight, under-exercised indoor cat. And for a male cat with any history of straining, know the emergency signs, because his margin is measured in hours.
What should I know about feline lower urinary tract disease (FLUTD) and urinary blockage?
A group of conditions causing painful, frequent, bloody or unproductive urination in cats. Costs for feline lower urinary tract disease (FLUTD) and urinary blockage run from $56 for routine vet checkup (wellness exam) to $2,395 for cat PU surgery (perineal urethrostomy). Which of the 4 procedures below your animal needs is what decides where you land.
Do urinary diets work?
Less than the marketing claims, and Cornell's wording is precise about the difference. Urinary diets may reduce the likelihood that a cat with idiopathic cystitis obstructs — and Cornell states there is no evidence they reduce the incidence of lower urinary tract signs themselves.
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.
- cat ultrasound cost $383–$880 — An ultrasound scan for a cat, most often a full abdominal study, sometimes with sedation and an ultrasound-guided sample taken at the same time.
- cat PU surgery (perineal urethrostomy) cost $995–$2,395 — Permanently widening a male cat's urethra after repeated urinary blockages, by removing the narrow penile section and creating a new, wider opening.
Related conditions
- 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.
- 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.
- 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.
- 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.
- 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 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.
- 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.
- 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.
- 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.
- 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.
