Skin and Coat Problems Groomers Should Spot (and When to Refer to a Vet)

The work itself explains it.

A groom runs your hands over the whole dog: the intake look-over, the bath, the clip-down, the dry, the brush-out, the nails, the ears, the tail.

The coat is open during that window.

Water flattens it, clippers remove it, and the dryer lifts it line by line, so skin that a thick coat hides at home is visible and touchable on the table.

That is why a groom doubles as a once-over — an informal groomer health check.

You part the coat, lift the ear flaps, handle the paws, open the mouth for the brush-out and lift the tail.

You are positioned to feel a lump, smell an ear or see a rash that is easy to miss in a full coat at home.

The professional habit is the sequence: notice, note, tell the owner, refer.

A groomer who runs that sequence protects the dog, the client relationship and the salon, and builds the judgment that comes with time in the trade.

What a groomer never does is the next step — naming the condition or treating it.

That work belongs to a licensed veterinarian.

New to the trade?

The dog groomer career guide covers what the role does day to day, where groomers work and how they train into the job.

Start before the water runs.

The intake look-over is when you find what is already sore: a hot spot — a raw, tender patch the dog flinches from — or an area clipped close at a previous groom that never settled.

Anything already inflamed changes how, and whether, you proceed, and it goes on the card before the bath.

The Merck Veterinary Manual's description of deep pyoderma gives you the reference signs for skin that has moved past irritation: pain, crusting, odor, and exudation of blood and pus.

A patch showing any of those hallmarks is not a shampoo challenge — it is a stop-and-refer finding.

Merck also lists draining tracts along the back — postgrooming furunculosis — as one presentation of deep pyoderma in dogs.

The name carries the setting: on the dorsum, after grooming.

Draining tracts across a dog's back get referred — the finding goes on the card and into the checkout conversation.

Ringworm is the finding with a second audience: you.

Merck lists its signs in dogs and cats as hair loss, scaling, crusting, redness, papules, hyperpigmentation and variable itch, and considers the disease zoonotic — in humans it causes skin lesions that are easily treated.

The CDC's advice for people around animals is plain: wash your hands after touching pets, and its ringworm guidance lists close contact with infected animals as a risk factor.

Yeast, dandruff and rashes show up without a name attached.

You meet them as coat that stays greasy or smelly after a proper bath, scale that flakes through the dry, or red and irritated patches that come to light during the bath and dry.

Your job stops at the description: what you saw, where on the body, and what the dog did when you touched it.

Picking a medicated shampoo to fix a skin condition is a treatment decision, and that is not the groomer's to make.

The clip-down is the lump detector.

Long coats hide growths; a clipped coat shows them.

When you find a lump, note where it sits, how big it is against something familiar, and what it looks like.

Then leave it alone: do not clip directly through it, do not squeeze it, and do not offer an opinion on what it is.

Referral is the whole move.

A new lump, a changed lump, or one the owner has never mentioned gets described at checkout, written on the card, and routed to their veterinarian.

Whether a growth matters is a veterinary question that starts with an exam — not a groomer's guess.

Ticks can turn up in the bath, the brush-out and the ear flaps.

Merck's removal guidance is the one to follow: fine-tipped tweezers, grasping the tick close to the skin, without twisting or crushing it; skip the folk remedies — nail polish, petroleum jelly, a hot match — and clean the bite area and your hands afterward.

Whether you remove a tick yourself or leave it for the owner is your salon's protocol to settle, but the owner hears about it either way.

Fleas and flea dirt show at the same stages.

The finding is not a judgment on the client — it is information.

Note it, tell the owner plainly, and follow your salon's sanitation protocol so it does not become a salon problem.

Ears first.

Merck lists pendulous ear flaps, narrow canals, hairy inner ear flaps and excessive hair in the canals among the ear-conformation factors that contribute to otitis externa.

That is why the ears you flip at the bath deserve a real look — odor, debris, redness, tenderness or a dog that jerks away all go on the card and into the checkout conversation.

Two ear findings deserve special handling.

A puffy, fluid-filled swelling on the inner ear flap is what Merck describes as an aural hematoma, and trauma from head shaking or ear scratching is almost always involved.

That is a refer — and a reason to handle the flap gently for the rest of the groom.

And before you reach for forceps on a hairy canal, know Merck's line: plucking ear hair is controversial, and hair that is not causing a problem should not routinely be removed, because removal can induce an acute inflammatory reaction.

This page stops at the referral line.

Eyes get the shortest list and the same rule: watering, redness, cloudiness, crusting or squinting are observations to note and refer — never something to drop anything into.

Teeth come with the sharpest scope line on the page.

The 2019 AAHA Dental Care Guidelines for Dogs and Cats say groomers and others should never be allowed to scale a pet's teeth — scaling belongs to trained veterinary personnel, in a clinical setting, on an anesthetized animal.

The American Veterinary Dental College's position statement says the same from its side: anyone other than a licensed veterinarian or a supervised, trained veterinary technician who provides dental services is practicing veterinary medicine without legal authority to do so.

So the groomer's work is to notice heavy tartar, bad breath, loose or broken teeth or bleeding gums, note it, and send it to the veterinarian.

Nails stay practical.

A quicked nail, a split or cracked claw, or paws too tender to handle are findings to record and mention at checkout, along with whatever your salon's injury policy covers.

What you never do is treat an injury beyond that policy, or hand out medical advice about it.

The anal area comes up because the tail lift and the final comb-out put it in front of you.

Merck lists scooting, licking or biting at the anal area, and painful defecation as clinical signs of anal sac disease.

One finding matters more than the rest: Merck says a firm, enlarged anal sac that cannot be expressed should raise suspicion of a tumor, which a biopsy confirms — a veterinary workup, full stop.

This page takes no side on whether and how a groomer expresses anal glands; the signs above go to the veterinarian.

Coat findings are the ones you are structurally best placed to catch, because you tend to see the same dogs on a schedule.

Hair that never grew back from last season's shave, thinning across the trunk that was not there at the last appointment, patchy loss with scale underneath — those are comparisons, and comparisons are exactly what a grooming card is for.

Post-clipping alopecia — hair that fails to regrow after clipping — is a recognized condition in the veterinary dermatology literature.

A 2020 study in Veterinary Dermatology described it as often having a clinically poor response to therapy.

That is the whole reason a regrowth concern is a referral and not a reassurance: the outcome is not something a groomer can promise, and the veterinary workup is how the cause gets sorted out.

What the veterinary literature we reviewed does not settle is the argument around shaving double coats.

Whether to clip a double-coated dog short is a judgment the groomer and owner make together; the strong claims on both sides of that debate outrun what that literature shows.

The recognized finding is regrowth failure.

Thinning with scale or crusting loops back to the skin section: those signs overlap with ringworm's list, and the zoonotic point comes with them.

Note the pattern, keep it on the card, and refer — with gloves on and hands washed, because ringworm travels between animals and people.

The script is description, not naming.

"There is a firm lump about the size of a grape on her left shoulder, and she did not react when I touched it" is a groomer's sentence.

"That is a lipoma" is a veterinarian's.

Every finding you report — a rash, an ear, a lump, a bald patch, a tooth — gets the same shape: what you saw, where it was, what the dog did, and that you would like their veterinarian to look at it.

Two lines hold no matter how experienced you get.

Sedation: the American Veterinary Dental College states that prescribing or administering anesthetic or sedative drugs by a non-veterinarian can be very dangerous and is illegal — if a dog cannot be groomed safely awake, that is a veterinary conversation, not a salon decision.

Scaling teeth: the AAHA guidelines and the AVDC position put scaling inside veterinary practice, so tartar findings are reported, never scraped.

The same discipline covers the smaller temptations: no medicated shampoo to treat a condition, no drops for an eye, no ointment on a sore, no diagnosis offered over the drying table.

Stopping is not under-serving the client — it is the scope.

Groomers who know exactly where their work ends are the ones owners and veterinarians trust with everything before that line.

And sometimes the right report comes mid-groom.

Pain that does not settle, bleeding, a finding that looks worse once the coat is off, a dog in visible distress — those pause the groom.

Safe the dog, contact the owner, and let the next step be theirs, with a veterinarian on the other end of it.

The card is where spotting becomes professional.

A finding that lives only in your memory is a finding the next groomer, the front desk and the owner's veterinarian never hear about.

Whatever your salon uses — a paper card, a booking app's notes field, a client history screen — the entries that matter are the same.

A useful finding entry answers four things: what you found and where on the body; how big or how extensive, in plain words; what the dog's reaction was; and what you told the owner and advised.

Add what you did — finished the groom, paused it, or stopped and asked the owner to collect the dog — and the referral is documented as well as the finding.

Then compare across visits.

The entry earns its keep the second time you see the dog: the lump that is unchanged, the ear that cleared up after the vet visit, the bald patch that spread.

That history is what a veterinarian wants behind "the groomer noticed something," and it turns a one-time observation into a record worth having.

Photos, if your salon's policy allows them, close the gap words leave: size, color and position, captured the same way each visit.

Follow the policy on consent and storage — the habit matters more than the equipment.

Write findings in the same words you say out loud: plain, specific, no diagnosis.

The card trains your eye as much as it records it.

Career information for grooming professionals, not veterinary, legal or insurance advice — skin, coat and health findings belong with the dog's veterinarian.
