Staph Infection in Puppies: Treatment and Cost

Crusty pustules on a puppy's hairless belly and groin, caused by the dog's own resident bacterium overgrowing. This is an emergency and needs a vet now if any of these are true: A puppy that is limp, cold, not nursing or not eating, alongside skin lesions; Spreading red, hot, painful swelling of the skin with a fever.

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.
   • A puppy that is limp, cold, not nursing or not eating, alongside skin lesions
   • Spreading red, hot, painful swelling of the skin with a fever
   • Collapse, or a puppy that cannot be roused
   • Skin lesions with vomiting, diarrhoea and rapid deterioration over hours
   • Extensive draining tracts with blood and pus in a puppy that is obviously unwell

   The rung exists because of one line in Merck: deep pyoderma is less common but more serious because it expands into the dermis, with a higher risk of bacteraemia. A puppy has little reserve, dehydrates fast and gets cold fast, so any skin infection combined with systemic illness is an emergency in a way that the same infection in a five-year-old dog is not. Merck's hallmarks of deep pyoderma - pain, crusting, odour and exudation of blood and pus - in a puppy that has also stopped eating is the picture to move on.

2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
   • Painful, hot, swollen skin with pus or a foul smell
   • Lesions spreading noticeably within a day
   • A fever, or a puppy that is quieter and eating less than yesterday
   • A raw, wet, rapidly enlarging patch - a hot spot
   • Deep lesions with hemorrhagic crusts or draining tracts
   • Any pyoderma in a puppy that is also scratching so hard it cannot rest

   Merck classifies surface pyoderma as including acute moist dermatitis - hot spots - and fold pyoderma, and these get worse by the hour rather than by the week. A puppy with a fever and skin lesions needs the whole picture assessed, not a tube of cream, because Merck's list of what must be ruled out includes demodicosis and dermatophytosis, both of which look like pyoderma and neither of which responds to an antibiotic.

3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
   • Small pustules, papules and crusts on the hairless skin of the belly and groin in an otherwise bright, growing puppy
   • Round, expanding rings of scale with a scabby edge - epidermal collarettes
   • Patchy hair loss with scale over the trunk
   • Pimples on the chin or lips
   • Skin infection that keeps returning after each course of treatment

   Book an appointment and ask for cytology. Merck calls impetigo the term for infection confined to non-follicular skin where the predominant lesions are pustules, and notes that in young dogs this is often called puppy pyoderma. The visit's value is in the exclusions rather than the diagnosis: a puppy with pyoderma needs deep skin scrapes for Demodex mites, because juvenile demodicosis presents exactly like this and treating it as a simple bacterial infection wastes weeks. The recurrent case is the one that needs a cause found rather than a fourth course.

4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
   • A few small pustules on the belly of a bright, growing, eating puppy already on a treatment plan
   • Lesions visibly resolving on medicated bathing over the first week

   Merck sets a clear review point: if there is no response after three to four days of treatment, the diagnosis should be reconsidered - not the dose increased. And treatment continues to clinical cure confirmed on a recheck examination, not to the end of the bottle. Merck lists antimicrobial undertreatment, meaning too low a dose or too short a course, among the commonest causes of recurrent pyoderma.

Crusty pustules on a puppy's hairless belly and groin, in a puppy that is otherwise bright and growing, is usually a cheap problem: a $56–$130 consultation and a medicated wash. The two things that make it expensive are misdiagnosis and a puppy that is also systemically unwell.

It is not the staph you are thinking of

Merck names Staphylococcus pseudintermedius as the primary pathogen in canine pyoderma, and it is a different species from the Staphylococcus aureus people carry. It is also already living on your dog — it is listed among the normal resident bacteria of canine skin.

Merck's explanation for why dogs get this and people mostly do not is anatomical: the canine stratum corneum and hair follicle are particularly susceptible to overcolonisation. Any condition that turns the normally dry skin environment into a moist one predisposes to it, which is why the classic sites are a puppy's hairless belly and a flat-faced dog's face folds.

The household question comes up and deserves a straight answer. Methicillin- resistant staphylococci do move between pets and people, which is why professional consensus guidelines on them exist — but S. pseudintermedius is dog-adapted and human infection is uncommon. The honest instruction is ordinary hand hygiene, not alarm, and we are not going to quantify a transmission risk we cannot source.

The test that has to happen at the first visit

Deep skin scrapes for Demodex mites. Juvenile generalised demodicosis presents exactly like puppy pyoderma, it does not respond to antibacterial treatment, and treating it as a simple bacterial infection wastes weeks at the age when weeks matter most.

Merck's position is that negative deep skin scrapings rule out follicular demodicosis in most cases. It is a five-minute in-house test and it changes the entire plan when it is positive.

Ringworm is the other exclusion, and Merck lists the ways to do it — a Wood's lamp, direct examination of hairs, fungal PCR, or culture. It is also contagious to people, which is a second reason not to assume.

Why the treatment is a wash rather than a tablet

Merck's recommendation is unambiguous and it is the opposite of what most owners expect: in most cases topical therapy should be the sole treatment for surface or superficial pyoderma, including cases with methicillin resistance. Systemic antimicrobials are reserved for deep pyoderma and the rare superficial case that cannot be managed topically.

The reason this is not a cost-saving compromise is in the same source. Merck records that canine superficial bacterial pyoderma is the single most frequent reason for antimicrobial use in small animal practice, and that with the spread of methicillin-resistant and multidrug-resistant Staphylococcus, empirical antibiotic selection has become increasingly difficult.

The protocol has numbers attached: medicated bathing two to three times weekly, with a contact time of ten to fifteen minutes each time, and other topical antimicrobials once or twice daily during active infection. Contact time is the part owners cut and the part doing the work.

Which shampoo, and what each one does

Merck lists the actives with their mechanisms, which is more useful than a brand name. Chlorhexidine at the concentrations used in veterinary shampoos coagulates bacterial cytoplasmic proteins, and at the higher end of that range it is antifungal as well. Benzoyl peroxide is an oxidising agent that is also degreasing and therefore drying, which makes it better suited to surface than to superficial infection. Chlorhexidine combined with miconazole is antistaphylococcal with antifungal activity, which matters because Malassezia is a common co-infection. Dilute sodium hypochlorite is well tolerated and has anti-inflammatory properties.

The choice is made off the cytology, not off the label. Yeast and cocci look different under a microscope and need different actives.

What if it is not getting better?

Merck sets a specific review point: if there is no response after three to four days of treatment, the diagnosis should be reconsidered — not the dose increased.

That is a short leash and a useful one. Three or four days is long enough to see whether an active infection is turning around and short enough that a missed demodicosis has not cost a month. The endpoint at the other end is a recheck examination confirming clinical cure, not the bottom of the bottle: Merck lists antimicrobial undertreatment, meaning too low a dose or too short a course, among the commonest causes of recurrent pyoderma.

If tablets are needed, one thing is worth knowing before they are dispensed: because S. pseudintermedius produces beta-lactamase, Merck says empirical use of penicillin, ampicillin and amoxicillin should be avoided, and most strains are also resistant to tetracycline and streptomycin. Leftover antibiotics from another dog are worse than nothing here.

When is a skin infection in a puppy an emergency?

When the puppy is ill as well as spotty. Merck flags deep pyoderma as less common but more serious, because it expands into the dermis with a higher risk of bacteraemia, and its hallmarks are pain, crusting, odour and exudation of blood and pus.

A puppy has little reserve. It dehydrates fast, it gets cold fast, and a skin infection combined with a limp, cold, non-nursing puppy is an emergency in a way the same infection in a five-year-old dog is not. What is being treated at that point is sepsis risk and dehydration, not the skin.

Why is it coming back?

Merck's list of the commonest causes of recurrent bacterial pyoderma is almost entirely fixable: failure to identify an underlying trigger, antimicrobial undertreatment, inappropriate immunosuppressive therapy, the wrong drug, the wrong dose, and failure to recheck the patient. Five of those six are avoided by the recheck appointment most owners skip.

Steroids are the one worth naming separately. Merck lists inappropriate use of glucocorticoids among the causes of recurrence, and notes that long-term steroid use is both comedogenic and immunosuppressive — so treating the itch while the infection is active makes the infection worse.

And a dog whose "puppy pyoderma" is still recurring at five years old is being investigated for the wrong disease. In an adult the leading explanation is allergic skin disease, and after that endocrine disease. Husbandry matters too: Merck notes lesions in confined dogs recur unless the dog comes off wire or concrete.

What it costs

The straightforward version is one of the cheapest things on this site, and that is the point of getting it right the first time.

The consultation with cytology and skin scrapes is $56–$130 nationally with $66 typical. That covers the examination, the slide that names the organism, the scrapes that exclude Demodex, and the ringworm testing — the four things that decide whether this is a two-week problem or a two-month one. A medicated shampoo is a fraction of one visit, and the recheck that confirms cure is another consultation.

The two branches that leave that band are both on the ladder above. An emergency assessment for a systemically ill puppy is $85–$150, typical $124, and what follows it is fluids and hospitalisation rather than a wash. And a biopsy at $144–$1,110, typical $465, is the answer when correct treatment has not worked and the exclusions are clean — a diagnosis rather than another antibiotic, and cheaper than the third course that would otherwise be dispensed.

Why staph skin infection in puppies (puppy pyoderma) happens

Staphylococcus pseudintermedius - the dog's own bacterium

Merck: the primary pathogen associated with pyoderma in dogs is Staphylococcus pseudintermedius, and it is listed among the normal resident bacteria of canine skin. It is not the human Staphylococcus aureus. Merck's explanation for why dogs get this and people mostly do not is anatomical: the canine stratum corneum and hair follicle are particularly susceptible to overcolonisation.

Warm, moist skin

Merck: any condition that changes the normally dry environment of the skin to a more moist one predisposes to overcolonisation, and warm moist sites - lip folds, facial folds, neck folds, armpits, interdigital areas, vulvar folds and tail folds - carry higher bacterial counts. That is why a puppy's hairless belly and a bulldog's face folds are the classic sites.

Demodicosis and other parasites

Merck lists parasitic disease, specifically demodicosis, among the underlying diseases behind complex recurrent pyoderma, and names demodicosis as commonly associated with deep pyoderma. Juvenile generalised demodicosis is a puppy disease and it looks like puppy pyoderma. This is the single most important thing to exclude at the first appointment.

Allergic skin disease

Merck's list of the commonest underlying triggers of superficial pyoderma in dogs begins with ectoparasites and allergies - atopic dermatitis, food allergy and flea bite allergy. In a puppy this is less likely than in an adult; in a dog that keeps relapsing into its second year it becomes the leading explanation.

Husbandry and hygiene

Merck names poor grooming among the common triggers, and its interdigital page notes that lesions in confined dogs are likely to recur unless the dog is removed from wire or concrete surfaces. Overcrowded, damp or dirty conditions in a breeding or rearing environment produce exactly this disease in a litter.

Steroids and immune suppression

Merck lists inappropriate use of glucocorticoids or other immunosuppressive therapy among the commonest causes of recurrent bacterial pyoderma, and notes that in interdigital disease long-term steroid use is both comedogenic and immunosuppressive and may worsen secondary bacterial pyoderma. Treating the itch with steroids while the infection is active makes the infection worse.

Methicillin resistance

Merck: with the spread of methicillin-resistant and multidrug-resistant Staphylococcus, treatment of pyoderma has become more challenging and empirical antimicrobial selection is increasingly difficult. Merck's own answer to that is not a stronger antibiotic - it is topical therapy, which it states should be the sole treatment for surface or superficial pyoderma including methicillin-resistant cases.

Endocrine disease in older dogs

Merck names hypothyroidism and hyperadrenocorticism among the internal diseases behind complex pyoderma. This does not apply to a twelve-week-old puppy and is included because a dog whose 'puppy pyoderma' is still recurring at five years old is being investigated for the wrong disease.

How a vet diagnoses staph skin infection in puppies (puppy pyoderma)

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.

Examination with skin cytology

Merck: microscopic evaluation of cytological preparations from skin lesions is one of the most valuable tools for diagnosing pyoderma, identifying both inflammatory cells and bacteria - and it also identifies Malassezia, a common co-infection. Samples come from an opened pustule or from under a lifted crust; clear adhesive tape is used for dry, oily or hard-to-reach sites. What it costs

Deep skin scrapes for Demodex

The exclusion that matters most in a puppy. Merck: negative deep skin scrapings rule out follicular demodicosis in most cases. It is a five-minute in-house test and it changes the entire treatment plan when it is positive.

Ringworm testing

Merck's list for ruling out dermatophytosis: a Wood's lamp, direct examination of hairs for hyphae or spores, fungal PCR assay, or fungal culture. Ringworm is contagious to people, which is a second reason not to assume.

Bacterial culture and susceptibility testing

Merck: particularly important in recurrent pyoderma and, because of antimicrobial resistance, essential to judicious selection of systemic therapy - with cytology performed from the same site to confirm bacteria are actually present. This is what identifies methicillin-resistant S. pseudintermedius rather than guessing at it.

Skin biopsy

For lesions that do not fit or that recur despite correct treatment, and to exclude immune-mediated disease such as pemphigus foliaceus, which Merck lists among the conditions behind complex pyoderma and which produces pustules that look bacterial. What it costs

Work-up for an underlying trigger

Merck: because pyodermas are triggered by underlying problems, appropriate diagnostic testing to identify underlying triggers is necessary. In a puppy that means parasites and husbandry; in a dog that keeps relapsing it means allergy and, later, endocrine testing.

How staph skin infection in puppies (puppy pyoderma) is treated

Topical therapy as the sole treatment

The headline recommendation, and it runs against what most owners expect. Merck: in most cases, topical therapy should be the sole treatment for surface or superficial pyoderma, including cases with methicillin resistance. Medicated bathing 2-3 times weekly with a contact time of 10-15 minutes each time; other topical antimicrobials once or twice daily during active infection; continue to clinical cure as determined at a recheck.

Choosing the right medicated shampoo

Merck's active ingredients, with what each does: chlorhexidine at 2-4%, which coagulates bacterial cytoplasmic proteins and is antifungal at 3-4%; benzoyl peroxide at 2.5-3%, an oxidising agent that is also degreasing and therefore drying, better for surface than superficial infection; 2% chlorhexidine with 2% miconazole, antistaphylococcal with antifungal activity; and sodium hypochlorite below 0.05%, well tolerated with anti-inflammatory properties.

The consultation that finds the trigger

Merck's list of the commonest causes of recurrent bacterial pyoderma opens with failure to identify an underlying trigger, then antimicrobial undertreatment, inappropriate immunosuppressive therapy, the wrong drug, the wrong dose, and failure to recheck the patient. Five of those six are avoided by the recheck appointment most owners skip. What the consultation that finds the trigger costs

Systemic antibiotics, reserved for deep infection

Merck: systemic antimicrobial therapy should be reserved for deep pyoderma and the rare superficial case that cannot be managed topically. First-tier drugs for a dog with no history of methicillin resistance are clindamycin at 11 mg/kg orally every 24 hours for up to 21 days, a first-generation cephalosporin such as cephalexin at 25-30 mg/kg orally every 12 hours for 21 to 42 days, or amoxicillin-clavulanate at 12.5-25 mg/kg orally every 12 hours for up to 30 days.

What not to prescribe empirically

Merck: because Staphylococcus pseudintermedius produces beta-lactamase, empirical use of penicillin, ampicillin and amoxicillin should be avoided, and most strains are also resistant to tetracycline and streptomycin. Second-tier agents such as fluoroquinolones should be chosen on culture and susceptibility results, not reached for first.

Emergency care for a systemically ill puppy

For the collapsed, cold, non-nursing puppy and for spreading cellulitis with a fever. What is being treated at that point is sepsis risk and dehydration, not the skin. What emergency care for a systemically ill puppy costs

Biopsy where the lesions do not behave

When correct treatment has not worked and the exclusions are clean, the answer is a diagnosis rather than another antibiotic. Merck's instruction for unusual or recurrent lesions is excision for histological examination. What biopsy where the lesions do not behave costs

Outlook and prevention

Straightforward puppy impetigo carries a good outlook: it is a surface and superficial infection, Merck's expectation is a response to topical therapy alone, and many puppies grow out of the underlying susceptibility as their skin matures. The risk sits in two places. The first is misdiagnosis - juvenile demodicosis and dermatophytosis both present this way and neither responds to antibacterial treatment, which is why the scrapes and the fungal testing at the first visit are not optional. The second is deep pyoderma, which Merck flags as more serious because it extends into the dermis with a higher risk of bacteraemia. Recurrence is common and Merck's reasons for it are almost all fixable: no underlying trigger identified, too short or too weak a course, concurrent steroids, the wrong drug, or no recheck. Merck notes canine superficial bacterial pyoderma is the single most frequent reason for antimicrobial use in small animal practice, which is why the profession's guidance has moved decisively towards topical treatment.

Keep the puppy's skin dry and clean, especially the belly, groin and any folds, and dry it properly after baths and wet walks. Keep whelping and rearing areas dry and hygienic, and get puppies off wire and bare concrete - Merck notes lesions in confined dogs recur unless the surface changes. Keep parasite control current and have any itchy puppy scraped for Demodex before it is treated for anything else. Do not use leftover antibiotics or another dog's medication: Merck's list of the reasons pyoderma recurs is dominated by the wrong drug, the wrong dose and too short a course, and the growth of methicillin-resistant Staphylococcus pseudintermedius is what has made those mistakes expensive. Wash your hands after handling lesions - the WAVD's consensus guidelines on methicillin-resistant staphylococcal infections in small animals exist precisely because these organisms move between animals and people in a household, though transmission is far less common than for the human-adapted Staphylococcus aureus. And go back for the recheck.

What treating staph skin infection in puppies (puppy pyoderma) costs

Costs for staph skin infection in puppies (puppy pyoderma) run from $56 for routine vet checkup (wellness exam) to $1,110 for dog biopsy. A severe case can run past the top of that range — what treatment adds depends on how bad it gets.

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 biopsy looks like

Dog Biopsy 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 staph skin infection in puppies (puppy pyoderma)?

Dog Biopsy is normally covered by a standard accident-and-illness policy. A biopsy taken to investigate a new problem is covered by an accident-and-illness policy; a biopsy taken as part of routine screening is not. The pre-existing rule bites in an unusual way here, because the biopsy is often the moment a condition is formally diagnosed - if the lump or the sign was already in the record before enrolment, the biopsy that names it is still investigating a pre-existing condition.

What you would get back: 70-90% of the covered bill after the deductible, where the sign being investigated first appeared after the waiting period ended.

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 staph skin infection in puppies (puppy pyoderma) — 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–$1,110 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 biopsy 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 biopsy cost $144–$1,110 — Taking a tissue sample from a dog and having a pathologist read it, priced from the laboratory fee upward rather than from a quote downward.

Related conditions

• dog colitis medication — Inflammation of the colon, which shows up as small, frequent, urgent stools carrying mucus and often fresh red blood, with straining.
• 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.
• dog wound treatment — Cleaning and closing a wound is mostly a timing decision, and the two things owners get wrong are both correctable in the first hour.
• dog skin yeast infection — Malassezia yeast lives on normal dog skin and only causes disease when something changes the skin it lives on.
• dog vomiting yellow — Yellow vomit is bile that has refluxed from the duodenum back into an empty stomach, and it is a description rather than a diagnosis.
• symptoms of blocked anal glands in dogs — Two small scent sacs sit either side of the anus and normally empty when a dog passes a firm stool.
• dog dementia treatment — An age-related degenerative brain disease that Cornell describes as causing deterioration similar to Alzheimer's disease in people, with beta-amyloid accumulating and neurons dying.
• dog coughing — A cough is a sign, not a diagnosis, and the same dry hack can come from an infection that clears itself in two weeks or from a failing heart valve.
• dehydrated dog treatment — Dehydration is not a disease, it is the measurable consequence of one, and the numbers behind it are published rather than guessed.
• dog diabetic symptoms — The pancreas stops making enough insulin, so glucose stays in the blood instead of feeding the cells, spills into the urine and drags water with it.
• dog diarrhea — Loose or watery stool, with or without blood, and the sixth most frequently recorded disorder in dogs in primary practice.
• dog ear infection treatment — Inflammation of the ear canal, almost always with a yeast or bacterial overgrowth on top of it.
• dog pregnancy symptoms — The signs owners read as pregnancy - weight gain, a swollen belly, mammary enlargement, milk, nesting behaviour - are produced just as reliably by a false pregnancy, and there is no home test that tells them apart.
• dog skin allergies — A lifelong immune reaction to ordinary environmental substances - pollens, moulds, dust mites, dander - that shows up as itching rather than sneezing.
• dog UTI symptoms — A bacterial infection of the bladder, usually Escherichia coli travelling up the urethra from the perineum.
• dog vomiting 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.
• parvo in dogs — A virus that destroys the lining of a puppy's intestine and the bone marrow that makes its white blood cells, producing vomiting and bloody diarrhoea that can kill in days.
• ringworm in dogs — Ringworm is a fungal infection of the hair and the surface of the skin, and the name is the first thing that misleads.
• dog seizures — A burst of abnormal electrical activity in the brain, which in its classic form drops the dog on its side with stiff, paddling limbs, frothing, loss of consciousness and often loss of bladder and bowel control.
• yeast infection in dogs — Malassezia pachydermatis is a yeast that lives on normal dog skin and in normal ears.
• kidney disease in cat symptoms — The kidneys lose function slowly and permanently, and the cruel arithmetic is that they hide it until most of them are gone.
• signs and symptoms of cat diabetes — A disease in which the cat's cells stop responding properly to insulin, so glucose stays in the blood instead of feeding the body.
• why is my cat meowing so much — Excessive meowing is a sign, not a disease, and it is the sign this dataset can be most useful about — because its differentials range from a cat that has learned meowing produces breakfast to a male cat that cannot pass urine and will die within about two days without treatment.
• cat coughing — A cough in a cat is a lower-airway problem until proved otherwise, and the commonest cause is asthma - an allergic narrowing of the small airways that Cornell puts at 1 to 5% of cats.
• urinary blockage cat — A group of conditions causing painful, frequent, bloody or unproductive urination in cats.
• worm cat symptoms — Worms in cats are usually silent, and the signs owners are told to look for - a dull coat, a potbelly, vomiting, diarrhoea - are the same signs as a dozen other things.
• worms in dogs — Four different worms with four different stories, grouped together only because they all live in a dog's gut.
• cat teeth disease — Three overlapping diseases, not one: gingivitis, which is reversible; periodontitis, which is not; and tooth resorption, in which the tooth dissolves from the inside out and which Cornell calls the most common cause of tooth loss in cats.
