Dog Pregnancy: Signs, False Pregnancy and Whelping

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. This is an emergency and needs a vet now if any of these are true: Strong, visible contractions for more than 30 minutes with no puppy delivered; More than 2 hours between puppies with no signs of contractions.

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.
   • Strong, visible contractions for more than 30 minutes with no puppy delivered
   • More than 2 hours between puppies with no signs of contractions
   • More than 30 minutes between puppies while the bitch is actively straining
   • Four hours of labour, strong or weak, with no puppy produced
   • Whelping that has now lasted more than 24 hours in total
   • Dark green, black or foul-smelling discharge before the first puppy arrives
   • Heavy vaginal bleeding before or during whelping
   • More than 70 days from a known breeding date with no labour
   • An unspayed bitch who is lethargic, off food and vomiting with a vaginal discharge, weeks after a season
   • Tremors, twitching, stiffness or a seizure in a nursing bitch

   Every threshold on this rung is Merck's, not a rule of thumb. Its criteria for dystocia include gestation beyond 70 days from a known breeding date, intervals over 30 minutes between puppies with contractions or over 2 hours without, active or weak labour beyond 4 hours with nothing produced, and total whelping duration beyond 24 hours; and it lists intense contractions for more than 30 minutes without a puppy, blackish-green discharge before whelping and profuse haemorrhage among the indications for a caesarean. Dark green discharge before the first puppy means the placenta has already separated. The unspayed-and-unwell bitch is pyometra, which Cornell calls a medical emergency that is deadly untreated. The tremoring nursing bitch is eclampsia, which Merck describes as acute and life-threatening, most often in a small-breed dog nursing a large litter at peak lactation two to three weeks after whelping.

2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
   • A hot, hard, painful mammary gland, or discoloured milk
   • Foul-smelling vaginal discharge in the days after whelping
   • A bitch who will not eat for 24 hours in late pregnancy or after whelping
   • Puppies that are crying constantly, cold, or losing weight after the first day
   • Panting and restlessness in a nursing bitch that is out of proportion to the room temperature

   Merck covers mastitis and metritis as distinct postpartum diseases of the bitch, and its differential list for eclampsia specifically includes excluding metritis and mastitis as other causes of irritability and fever. Panting and restlessness are Merck's named early clinical signs of eclampsia, before the tremors start - which is the point at which the drive is short and the outcome is good. On the puppies: Merck's owner guidance is to weigh them as soon as they are dry and then twice daily for the first week, because any weight loss after the first 24 hours indicates a problem.

3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
   • You think your dog may be pregnant and want to know
   • A planned litter that needs a count before whelping day
   • Mammary development, milk, nesting and weight gain in an unspayed bitch four to nine weeks after a season, with no known mating
   • An unplanned mating you want assessed

   Book an appointment rather than waiting to see. Merck's timings are specific: abdominal palpation detects pregnancy at about day 21, a relaxin blood test from day 30 to 35, ultrasound reliably from 25 to 35 days with the advantage of confirming the foetuses are alive, and radiographs after about day 45, with films taken after day 55 the best way to count the litter. That count is the single most useful thing to have on whelping night, because it is how you know whether a puppy is still inside.

4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
   • A confirmed pregnancy progressing normally in the last fortnight
   • A rectal temperature that has dropped, with no contractions yet
   • Stage I labour: restlessness, nesting and panting, with no visible straining

   Merck: a drop in rectal temperature usually precedes delivery by about 8 to 24 hours, and Stage I lasts 12 to 24 hours, with contractions beginning but not visible externally. Merck's dystocia criteria also include whelping not observed within 24 to 36 hours after the temperature drop. Take the temperature twice daily from day 55 so you know what this bitch's baseline is - a single reading tells you nothing without one.

Every sign on the standard "is my dog pregnant" list — weight gain, a swelling belly, enlarged mammary glands, milk, nesting — is produced just as reliably by a false pregnancy. That is not a caveat. It is the reason there is no home test for this, and it is where a plan has to start.

Why there is no canine home pregnancy test

Merck records the mechanism plainly: unlike other species, the canine corpus luteum continues producing progesterone for the length of gestation regardless of pregnancy status. The hormone a home test would measure behaves identically in a bitch who conceived and one who did not.

Merck goes further on the false-pregnancy side — physiologically, all non-pregnant bitches are pseudopregnant at the end of dioestrus, and where the signs are conspicuous it is called overt pseudopregnancy. Merck states there are no specific diagnostic tests for it, because hormonal assays are non-diagnostic.

So the answer comes from imaging or from one specific blood test, and from nothing you can do at home.

What actually confirms it, and when

Four windows, and they do not overlap much. Merck's timings: abdominal palpation at about day 21, a relaxin blood test from day 30 to 35, ultrasound reliably from 25 to 35 days, and radiographs after about day 45.

Ultrasound does something the others cannot — Merck notes it also confirms the foetuses are alive. Radiographs do something ultrasound cannot: films taken more than 55 days into pregnancy are the best way to count the litter.

That count is the single most useful thing to have on whelping night, because it is how you know whether a puppy is still inside.

Sixty per cent of misbred dogs are not pregnant

This is Merck's figure and it is the reason the first step after an unplanned mating is a test rather than a treatment. Merck states that pregnancy should always be confirmed before any intervention, because 60% of misbred dogs do not become pregnant at all.

It also notes that detecting sperm in the vaginal vault confirms only that a mating happened, not that a pregnancy exists. One ultrasound at the right point in the calendar avoids a great deal of unnecessary treatment.

The whelping thresholds, written down

These are Merck's criteria for dystocia, not rules of thumb, and they are the part of this page worth printing and putting on the fridge before the night arrives.

Strong, visible contractions for more than 30 minutes with no puppy delivered. More than two hours between puppies with no contractions, or more than 30 minutes between puppies while she is actively straining. Four hours of labour, strong or weak, with nothing produced. A total whelping duration beyond 24 hours. More than 70 days from a known breeding date with no labour. And whelping not observed within 24 to 36 hours after the temperature drop.

Dark green, black or foul-smelling discharge before the first puppy is its own line: it means the placenta has already separated. Merck lists that, profuse haemorrhage, and intense contractions for over 30 minutes with no puppy among the indications for a caesarean.

Is dystocia common?

At about 5% of pregnancies overall, no — but Merck adds that it may approach 100% in some achondroplastic and brachycephalic breeds. That range is why an average is useless here and breed is not.

Merck gives no breed list with the near-100% figure and neither will we. What it means practically is that a flat-faced or short-legged bitch should have the emergency clinic's number, the litter count and these thresholds settled before week nine, and an owner of a mixed-breed farm dog can plan on an ordinary whelping and be ready to be wrong.

The advice that makes eclampsia more likely, not less

Oral calcium during pregnancy. Merck states that calcium supplementation during gestation is not indicated and may cause rather than prevent postpartum hypocalcaemia, because excess calcium downregulates the calcium regulatory system so the bitch cannot mobilise her own reserves when lactation peaks.

That is the opposite of common breeder advice. Eclampsia is acute and life-threatening, Merck describes it most often in a small-breed dog nursing a large litter two to three weeks after whelping, and the early signs are panting and restlessness before any tremor — which is the point at which the drive is short and the outcome is good.

Feed a properly balanced diet instead, food and water ad lib during lactation, and weigh the puppies twice daily for the first week: Merck notes any weight loss after the first 24 hours indicates a problem.

The impersonator that kills

Pyometra. Cornell describes it as a life-threatening infection filling the uterus with pus, most commonly from E. coli ascending during the heat cycle when the cervix is relaxed, typically appearing one to two months after the previous season.

It presents as exactly what an owner expects a pregnancy to look like from the outside: an unspayed bitch, weeks after a season, with a swelling belly and a change in behaviour. The differences are that she is unwell — lethargic, off food, often vomiting, often drinking more — and that a closed-cervix pyometra produces the more severe illness precisely because there is no discharge to see.

Cornell's treatment is surgical removal of the ovaries and uterus with intravenous fluids and antibiotics, and notes the operation is often more complicated than a routine spay. Medical management with prostaglandins is generally discouraged except for a young, valuable breeding bitch, is not an option for a critically ill or closed-cervix dog, and frequently ends in recurrence.

What premature does not mean in dogs

Merck records something that changes how an early caesarean is discussed: puppies cannot be born prematurely and survive, because meaningful surfactant production happens late, from 57 to 60 days.

There is therefore no safe way to end a difficult pregnancy early. That is the argument for the litter count on radiograph after day 55 and for taking the temperature twice daily from around day 55 — a drop usually precedes delivery by about 8 to 24 hours, and a single reading tells you nothing without a baseline for this particular bitch.

Merck's one reassurance for a breeder facing a first surgical delivery is worth carrying: a bitch who needs one caesarean does not invariably need one for every future litter.

Why this page is shaped like a disease page

Because our condition template was built for diseases, and pregnancy is not one. We are saying so rather than pretending otherwise. The triage ladder fits well, because dystocia and eclampsia have published numeric thresholds that decide whether puppies live. The diagnostics fit, because confirming a pregnancy is a real test sequence with real prices.

The section headed "why it happens" below is being used for the differential behind what an owner notices — true pregnancy, false pregnancy, pyometra, or something else entirely — rather than for the causes of a disease. And "prevention" does not fit at all: you do not prevent pregnancy the way you prevent an ear infection, so that field covers preventing an unplanned litter, preventing pyometra and preventing eclampsia instead.

What each step costs, and the one we cannot price

The confirmation is the cheap part. An abdominal ultrasound is $383–$880 nationally with $483 typical, and it is the test that both confirms the pregnancy and tells you the foetuses are alive. The emergency assessment that starts a dystocia work-up is $85–$150.

The expensive outcomes are the two this page is trying to keep you away from. Pyometra surgery is $500–$4,000, typical $1,218 — Cornell's point is that spaying a young healthy dog is both safer and cheaper than an emergency pyometra spay later, and a routine spay is $75–$874, typical $455.

The honest gap: we do not yet publish a price record for a canine caesarean section, which is the single most likely large bill on whelping night. The emergency-visit figure in the section below is the assessment, not the surgery, and it should not be read as standing in for it.

Why dog pregnancy, false pregnancy and whelping happens

An actual pregnancy

Merck: gestation lasts about 62 to 64 days in dogs, though predicting the delivery date is difficult because the breeding date does not always match the conception date, and length varies with breed and litter size. Fresh normal sperm can survive up to seven to nine days in the female tract, which is why the breeding date is a poor proxy for the conception date.

False pregnancy (pseudopregnancy)

The reason the signs alone cannot answer the question. Merck: physiologically, all non-pregnant bitches are pseudopregnant at the end of dioestrus, and the intensity of signs varies enormously - some show none, others show conspicuous signs, which is called overt pseudopregnancy. The physical signs are weight gain, mammary enlargement and milk secretion, with restlessness, anorexia, reduced activity, abdomen licking, aggression and maternal behaviour. Merck states plainly that there are no specific diagnostic tests, because hormonal assays are non-diagnostic.

Progesterone that rises whether or not she conceived

The mechanism behind the confusion. Merck: unlike other species, the canine corpus luteum continues producing progesterone for the length of gestation regardless of pregnancy status. There is no canine equivalent of a home pregnancy test because the hormone that would drive one behaves identically in a pregnant and a non-pregnant bitch.

Pyometra

The dangerous impersonator. Cornell: a life-threatening infection filling the uterus with pus, most commonly caused by E. coli ascending during the heat cycle when the cervix is relaxed, typically appearing one to two months after the previous season. Repeated cycles thicken the uterine lining into cystic endometrial hyperplasia, and toxins leaking into the bloodstream do the killing. A closed-cervix pyometra produces the more severe illness because there is no discharge to see.

Something else entirely

Abdominal enlargement also comes from obesity, abdominal fluid, an enlarged organ or a mass. Merck's note on unplanned matings is a useful counterweight to owner assumptions: pregnancy should always be confirmed before any intervention, because 60% of misbred dogs do not become pregnant at all.

How a vet diagnoses dog pregnancy, false pregnancy and whelping

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.

Abdominal palpation

Merck: pregnancy can be detected by palpation of the uterus at about day 21 of gestation. It is free, it happens during a normal consultation, and it has a narrow window - the foetal swellings become harder to feel again as the pregnancy advances. What it costs

Relaxin blood test

Merck: a blood test measuring the hormone relaxin can detect pregnancy by day 30 to 35 of gestation. It is the closest thing to a pregnancy test that exists in this species, and it is the test Merck names as one of the two acceptable ways to confirm pregnancy before any intervention.

Abdominal ultrasound

Merck: ultrasonography reliably detects pregnancy by 25 to 35 days and also allows confirmation that the foetuses are alive. That second part is what a radiograph cannot do, and it is the reason ultrasound is the test of choice if there is any concern rather than simple curiosity. What it costs

Radiographs for the litter count

Merck: the developing foetuses can be seen on x-rays after about day 45, and films taken more than 55 days into pregnancy are the best way to determine litter size. Skeletal mineralisation is what makes them visible, which is why the timing is fixed and not negotiable.

Assessment of a bitch in trouble during whelping

Merck's work-up for suspected dystocia: history and physical examination, abdominal palpation for foetal number and movement, vaginal examination for an obstruction or a puppy in the birth canal, blood work including packed cell volume, total solids, glucose and ionised calcium, a progesterone measurement, and lateral and ventrodorsal radiographs. Ultrasound determines foetal viability - a normal foetal heart rate is 200 to 250 beats per minute. What it costs

How dog pregnancy, false pregnancy and whelping is treated

Confirming the pregnancy before doing anything

Merck is explicit that no intervention should proceed until pregnancy is confirmed by ultrasound or relaxin assay - and that in a reported mismating, detecting sperm in the vaginal vault confirms only that a mating happened, not that a pregnancy exists. With 60% of misbred dogs not becoming pregnant, this single step avoids a great deal of unnecessary treatment. What confirming the pregnancy before doing anything costs

Managing a false pregnancy

Merck: pseudopregnancy is treatable with a good prognosis and most clinical signs resolve without treatment. Where lactation needs stopping, prolactin inhibitors are used - cabergoline in dogs at 5 mcg/kg orally every 24 hours for 5 to 10 days. Two practical instructions: do not milk out the mammary glands, because that only stimulates more lactation, and phenothiazine sedatives are not recommended because they stimulate prolactin.

Medical management of uterine inertia

Merck: where imaging shows the dystocia is not obstructive, oxytocin at 2-5 units per animal at 20-30 minute intervals for no more than three doses, with 10% calcium gluconate 0.5-1.5 mL/kg given slowly intravenously ten minutes beforehand because calcium increases contraction strength and works synergistically. Merck warns that oxytocin may cause premature placental separation and must not be used in obstructive dystocia. This is a veterinary decision, not a home one.

Emergency assessment and caesarean section

Merck's indications include systemic illness in the dam, unaddressed dystocia, blackish-green discharge before whelping, profuse haemorrhage, intense contractions for over 30 minutes with no puppy, primary or secondary uterine inertia not responding to medical treatment, abnormalities of the pelvis or birth canal, relative foetal oversize, malposition that cannot be corrected, and foetal death with putrefaction. Merck adds a note owners rarely hear: a bitch who needs one caesarean does not invariably need one for every future litter. What emergency assessment and caesarean section costs

Emergency spay for pyometra

Cornell: pyometra is best treated by surgical removal of the ovaries and uterus, alongside intravenous fluids and antibiotics, and the surgery is often more complicated than a routine spay. Medical management with prostaglandins is generally discouraged except for a young, valuable breeding bitch, is not an option for a critically ill or closed-cervix dog, and frequently ends in recurrence. What emergency spay for pyometra costs

Treating eclampsia

Merck: slow intravenous 10% calcium gluconate at 0.5-1.5 mL/kg over 10-30 minutes, with the heart monitored for bradycardia and arrhythmias, usually producing clinical improvement within 15 minutes. Puppies should not nurse for 12-24 hours afterwards and are fed a milk replacer; if tetany recurs during the same lactation the litter comes off the bitch entirely. Owners should be warned that eclampsia is likely to recur with future pregnancies.

Spaying

Prevention rather than treatment, and the intervention that removes pyometra, unplanned litters and pseudopregnancy at once. Cornell: pyometra is entirely preventable by spaying before infection develops, and having a dog spayed while young and healthy is safer and less costly than waiting for an emergency pyometra spay. Merck's timing note is that spaying during the luteal phase can itself precipitate a false pregnancy, so anoestrus is the preferred window. What spaying costs

Outlook and prevention

Most canine pregnancies proceed without intervention. Merck puts the overall incidence of dystocia at approximately 5% of pregnancies, but notes it may approach 100% in some achondroplastic and brachycephalic breeds - which is why breed, not average, is what a plan should be built on. Pseudopregnancy carries a good prognosis and mostly resolves untreated once the hormonal cause has passed. Pyometra has a good prognosis when diagnosed and treated with surgery early, per Cornell, and is deadly untreated, with a worse outlook once sepsis or uterine rupture has occurred. Eclampsia responds to intravenous calcium within about 15 minutes but is life-threatening if it progresses to seizures and coma, and Merck notes a bitch may remain unresponsive after the calcium is corrected if cerebral oedema has developed. Merck also records that puppies cannot be born prematurely and survive - meaningful surfactant production happens late, from 57 to 60 days - which is why an early caesarean is not a safe way to end a difficult pregnancy.

Spay if you are not breeding: it prevents unplanned litters, pseudopregnancy and pyometra, and Cornell notes that spaying a young healthy dog is both safer and less costly than an emergency pyometra spay later. If you are breeding, plan the diagnostics rather than improvising them - confirm by ultrasound at 25-35 days, count the litter by radiograph after day 55, take the bitch's temperature twice daily from around day 55, and have the emergency clinic's number and the whelping thresholds written down before the night arrives. One piece of common breeder advice is actively harmful: Merck states that oral calcium supplementation during gestation is not indicated and may cause rather than prevent postpartum hypocalcaemia, because excess calcium during pregnancy downregulates the calcium regulatory system so that the bitch cannot mobilise her own reserves when lactation demands peak. Feed a properly balanced diet instead, provide food and water ad lib during lactation, and start supplementing the puppies with milk replacer early and solid food from three to four weeks.

How common it is: approximately 5% of pregnancies, but may approach 100% in some breeds — Bitches and queens; Merck Veterinary Manual's stated overall incidence of dystocia, with the near-100% figure applying to achondroplastic and brachycephalic types. Source.

What treating dog pregnancy, false pregnancy and whelping costs

Costs for dog pregnancy, false pregnancy and whelping run from $56 for routine vet checkup (wellness exam) to $4,000 for dog pyometra surgery. Which of the 5 procedures below your animal needs is what decides where you land.

What the invoice for dog pyometra surgery looks like

Dog Pyometra 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 dog pregnancy, false pregnancy and whelping?

Dog Pyometra Surgery is normally covered by a standard accident-and-illness policy. Pyometra is a sudden illness in an intact female dog and is normally covered by an accident-and-illness policy once the waiting period has passed, since it cannot plausibly be pre-existing in a previously healthy dog. The practical problem is timing rather than coverage: it presents out of hours, payment is usually required before surgery, and reimbursement arrives afterwards. We could not verify a pyometra-specific reimbursement figure against any carrier's own published document, so the figure below is the general accident-and-illness structure.

What you would get back: 70-90% of the covered bill after the annual deductible, under a standard accident-and-illness policy.

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 dog pregnancy, false pregnancy and whelping — 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–$4,000 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 pyometra surgery shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.

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 ultrasound cost $383–$880 — An ultrasound scan for a dog, most often a full abdominal study, sometimes with sedation and an ultrasound-guided sample taken at the same time.
• dog pyometra surgery cost $500–$4,000 — Emergency removal of an infected uterus in an unspayed dog - the same operation as a spay, but performed on a systemically ill patient, usually out of hours.
• dog spay or neuter cost $75–$874 — Elective sterilisation of a dog - ovariohysterectomy for females, castration for males - performed under general anesthesia.

Related conditions

• dog colitis medication — Inflammation of the colon, which shows up as small, frequent, urgent stools carrying mucus and often fresh red blood, with straining.
• dehydrated dog treatment — Dehydration is not a disease, it is the measurable consequence of one, and the numbers behind it are published rather than guessed.
• dog 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 UTI symptoms — A bacterial infection of the bladder, usually Escherichia coli travelling up the urethra from the perineum.
• dog vomiting and diarrhea — Sudden vomiting, usually with diarrhoea, from an inflamed stomach and intestine.
• dog vomiting blood — Blood in a dog's vomit - fresh red, dark clots, or the brown grit that looks like coffee grounds because the stomach has already digested it.
• parvo in dogs — A virus that destroys the lining of a puppy's intestine and the bone marrow that makes its white blood cells, producing vomiting and bloody diarrhoea that can kill in days.
• dog seizures — A burst of abnormal electrical activity in the brain, which in its classic form drops the dog on its side with stiff, paddling limbs, frothing, loss of consciousness and often loss of bladder and bowel control.
• dog vomiting yellow — Yellow vomit is bile that has refluxed from the duodenum back into an empty stomach, and it is a description rather than a diagnosis.
• dog dementia treatment — An age-related degenerative brain disease that Cornell describes as causing deterioration similar to Alzheimer's disease in people, with beta-amyloid accumulating and neurons dying.
• dog coughing — A cough is a sign, not a diagnosis, and the same dry hack can come from an infection that clears itself in two weeks or from a failing heart valve.
• dog ear infection treatment — Inflammation of the ear canal, almost always with a yeast or bacterial overgrowth on top of it.
• dog eye allergies — A red, weeping, itchy eye is what owners call an eye allergy, and environmental irritants and allergens genuinely are, in Merck's words, common causes of conjunctivitis in all species.
• hip dysplasia in dogs — An inherited malformation in which the hip joint is too loose, so the ball grinds in the socket and arthritis follows.
• ivdd in dogs — A disc between the vertebrae ruptures or bulges and presses on the spinal cord, causing pain, wobbliness or paralysis.
• kennel cough in dogs — A contagious inflammation of the windpipe and airways caused by a mix of viruses and bacteria, not by one organism.
• dog limping — Limping means something painful is interfering with the normal use of a limb, and Cornell's framing is that it deserves veterinary attention rather than a wait-and-see.
• staph infection in puppies — Crusty pustules on a puppy's hairless belly and groin, caused by the dog's own resident bacterium overgrowing.
• dog wound treatment — Cleaning and closing a wound is mostly a timing decision, and the two things owners get wrong are both correctable in the first hour.
• dog skin yeast infection — Malassezia yeast lives on normal dog skin and only causes disease when something changes the skin it lives on.
• kidney disease in cat symptoms — The kidneys lose function slowly and permanently, and the cruel arithmetic is that they hide it until most of them are gone.
• signs and symptoms of cat diabetes — A disease in which the cat's cells stop responding properly to insulin, so glucose stays in the blood instead of feeding the body.
• why is my cat meowing so much — Excessive meowing is a sign, not a disease, and it is the sign this dataset can be most useful about — because its differentials range from a cat that has learned meowing produces breakfast to a male cat that cannot pass urine and will die within about two days without treatment.
• cat coughing — A cough in a cat is a lower-airway problem until proved otherwise, and the commonest cause is asthma - an allergic narrowing of the small airways that Cornell puts at 1 to 5% of cats.
• urinary blockage cat — A group of conditions causing painful, frequent, bloody or unproductive urination in cats.
• worm cat symptoms — Worms in cats are usually silent, and the signs owners are told to look for - a dull coat, a potbelly, vomiting, diarrhoea - are the same signs as a dozen other things.
• symptoms of blocked anal glands in dogs — Two small scent sacs sit either side of the anus and normally empty when a dog passes a firm stool.
• dog skin allergies — A lifelong immune reaction to ordinary environmental substances - pollens, moulds, dust mites, dander - that shows up as itching rather than sneezing.
• worms in dogs — Four different worms with four different stories, grouped together only because they all live in a dog's gut.
• ringworm in dogs — Ringworm is a fungal infection of the hair and the surface of the skin, and the name is the first thing that misleads.
• yeast infection in dogs — Malassezia pachydermatis is a yeast that lives on normal dog skin and in normal ears.
• cat teeth disease — Three overlapping diseases, not one: gingivitis, which is reversible; periodontitis, which is not; and tooth resorption, in which the tooth dissolves from the inside out and which Cornell calls the most common cause of tooth loss in cats.
