Seizures, Heart Murmurs, Sedatives: Health Conditions Owners Forget to Mention

The bark from the drying table

Groomers who have heard it say they know it straight away: a seizure bark, which doesn’t sound like any other bark. In one salon, a dog started seizing on the dryer, and a junior groomer who heard it had the dryer off within seconds.

Seizures come up in grooming threads far too often. So do heart murmurs, heart failure pills, and a fainting spell “last week” that the family mentions only after something has gone wrong.

Most owners aren’t lying. They think of grooming as a bath and a haircut, not a stressful hour with heat, noise and a stranger’s hands, so a daily pill doesn’t seem worth mentioning. The 15 questions in our grooming check-in get the answers out. This post covers what to do with them: which conditions change the groom, when to ask for a vet’s sign-off, and what to put in writing.

This is general guidance from groomers’ experience, not veterinary advice. If you’re unsure about a particular dog, the owner’s vet is the right person to ask.

What actually changes on your table

A condition usually matters to a groomer for one of four reasons: it’s made worse by stress, by heat, by time on the table, or by handling in a particular place.

Some problems show up as a change in mood rather than a symptom, which is why a normally chatty dog going quiet at drop-off is worth writing down.

Read the medication list, not the tick box

An owner who ticks “no health issues” will often still give you a medication name if you ask, because they don’t connect the pill with a condition. The name tells you what to ask next. You aren’t diagnosing anything, and some of these drugs have several uses.

Write the drug and the reason in the dog’s record, not just “on meds.” The groomer who has this dog in six months needs both.

Sedatives: the condition you can’t see

One owner brought in a doodle on trazodone and described the dog’s sleepy state as his “baseline.” It’s a common story. A sedated dog looks easier, but groomers warn about two problems. It can bite without the usual warnings, because the behavior that would have told you to stop has been turned down. And sedation can hide the early signs of a medical emergency, so the dog who would normally have panted or struggled just goes quiet.

Acepromazine is the one groomers object to most. Many refuse dogs on it, because it stops the dog moving without taking away the fear.

Your policy doesn’t have to be a ban, but decide it in advance. If you accept sedated dogs, set these rules:

• The sedative is prescribed by a vet for grooming, not left over from a past procedure.
• The owner tells you the drug, the dose and the time given, at booking and again at drop-off.
• The dog is never left alone on the table, in the tub or on the dryer.
• You never give a dog anything yourself, even if the owner asks you to.

How sedation fits with handling difficult dogs is a bigger decision, and it belongs in your salon’s bite policy.

Groom, adapt, ask the vet, or decline

The worst time to decide is at the desk, with the owner watching. Set your four categories in advance so anyone at your salon gives the same answer.

Groom as normal. A managed condition that doesn’t change the work, such as a skin allergy or a mild ear problem. Note it and carry on.

Adapt the groom. The dog can be groomed if you change the slot. A quieter time, a shorter service, no high-velocity dryer near the head, or a towel dry. Say so when you book, so the owner isn’t surprised to get a simpler service.

Vet sign-off first. Ask for this when any of these apply:

• A recent seizure, or seizures that have become more frequent
• A heart condition the vet has graded or is treating
• Fainting or collapse, especially if nobody has found the cause
• Breathing problems at rest
• Surgery in the last few weeks
• A very old or frail dog on several medications

Decline, or stop. A dog that is struggling to breathe, collapses or seems unwell at drop-off shouldn’t be groomed that day. The same goes for a dog whose owner won’t answer your questions. As groomers who have ended a groom early put it, a half-finished haircut beats the ER.

How to ask for vet sign-off

Owners sometimes hear “I need a vet note” as “I don’t want your dog.” The way you say it matters:

“We’d love to keep seeing Bella. Grooming means heat, noise and time on her feet, so with her heart condition I’d like her vet to tell us what’s safe. Could you ask them? If they’re happy, we’ll work to whatever they suggest.”

Ask for it in writing. An email or a note on the clinic’s letterhead is enough if it covers:

• The dog’s name and the condition
• That the vet knows the dog is being professionally groomed
• Any limits, such as no high-velocity dryer or a maximum time on the table
• Who to call if something goes wrong

A sign-off doesn’t remove all the risk, and it doesn’t mean nothing can go wrong. But it does show you asked. A vet in one of the r/doggrooming threads put it bluntly: if it isn’t documented in the record, it didn’t happen. The same rule protects you when an owner later says the groom caused the problem.

A health disclosure clause to copy

Your intake form gets the answers. The clause makes the owner responsible for keeping them up to date. Add this to your pet service agreement or your consent and release form:

Health disclosure. I have told [Salon] about all health conditions, medications and recent vet visits I know of for my dog, including any seizures, heart or breathing problems, fainting, diabetes or recent surgery. I will tell [Salon] before each visit if anything has changed, and if my dog has been given any sedative or calming medication, I will say which one, how much and when.

I understand that grooming can be stressful, and that [Salon] may shorten, stop or decline a groom if my dog appears unwell or unsafe to continue. I will pay for the work completed. If [Salon] asks for written approval from my vet, grooming will wait until I provide it.

Have someone who knows your state’s law look it over. Then ask the owner to read it again whenever their dog’s health changes, not just at the first visit.

If something goes wrong on the table

Agree this with your staff before you need it, and put it on the wall:

1. Stop everything. Dryer off, clippers off, and turn down the noise and light if you can.
2. Keep the dog safe. Keep them away from table edges and the tub. Don’t put your hands near the mouth of a dog having a seizure.
3. Time it, and film it if you can. Vets will ask how long it lasted.
4. Call the owner, then the vet. Keep the number of your nearest emergency clinic with the owner’s vet details. A seizure lasting more than about five minutes, repeated seizures, trouble breathing or collapse means go straight to the emergency vet.
5. Write it down the same day. Note the time, what you were doing, what you saw and who was there.

In a van, step four matters even more. You may be alone and a long way from the clinic you know, so check the nearest emergency vet for each area day.

Keep the answer where the next groomer will see it

A health answer only helps if it reaches the person holding the dryer. On a paper form in a folder, it won’t. The same goes for a note buried in old visits, the problem covered in haircut notes that actually get used.

In Packyard, health notes and your own color-coded pet codes (one for seizures, say) stay on the pet’s profile and show wherever the pet does, so the warning reaches the groomer before the dog is on the table.

For dogs whose problem is behavior rather than health, see how to set a muzzle policy. A sudden snap from a usually easy dog can be a health problem that nobody has found yet.
