What to Do About a Kennel Cough Outbreak at Your Dog Daycare

A dog coughs in the play yard at 10 a.m. By noon, two more are hacking. You're now trying to decide whether to close, what to tell eleven owners, and whether you did something wrong.

Take a breath. Coughing dogs in a group setting are common, and a plan beats panic. This is the order we'd work in. Anything medical is your vet's call, not ours, so the plan below keeps leaning on them.

First hour: stop the spread you can stop

Kennel cough is a catch-all name for several respiratory infections that spread easily where dogs share air and surfaces. You can't know from the doorway which germ it is, and you don't need to. What you need is to cut contact.

1. Pull the coughing dog out of group play. Put the dog in a separate room or an owner pickup area, away from other dogs.
2. Call the owner and ask them to pick up and call their vet. Don't diagnose. Say what you saw: "He's had a dry, honking cough since this morning and we'd like your vet to look at him."
3. Note who's been near that dog. Which play group, which water bowls, which room. You'll want that list in an hour.
4. Call your own vet (the one you work with, not the sick dog's). Describe what's happening and ask what they'd have you do about the rest of the dogs on site, and for how long.
5. Clean the area. Wash and disinfect with a product made for animal facilities, following the label for contact time. Replace shared water bowls with fresh ones, and wash toys that were in the room. See our cleaning protocol for the routine.

Don't hide it. If you handle it quietly, the owners will find out from each other anyway, usually in a worse version.

Same day: who to tell and what to say

Tell the owners of dogs who were in the same group or room first, then everyone booked for the next few days. A short, factual note works better than a long one. Include:

• What you saw (coughing in one or more dogs).
• What you did (separated, cleaned, called your vet).
• What they should watch for at home.
• What you'd like them to do (call their vet if their dog coughs, tell you right away).
• What happens next at the daycare.

Here's a sample you can copy and change.

Subject: Coughing dogs at [Daycare Name], what we're doing

Hi [Owner name],

Today we noticed a few dogs with a dry cough at [Daycare Name]. We sent
the affected dogs home, cleaned and disinfected the play areas, and
spoke with our veterinarian about next steps.

Your dog was in [Group/Room] with one of the coughing dogs, so we want
you to know. Please watch for coughing, gagging, sneezing, a runny nose,
low energy or a drop in appetite over the next couple of weeks. If you
see any of these, call your vet and let us know.

If you are worried about your dog, your vet is the best person to ask
about testing, treatment and vaccines. We can't give medical advice.

For now, [we are open as usual / we are closed until DATE / we are
asking that dogs with any cough stay home]. We'll update you by [day].
Please call us at [phone] with any questions.

Thank you,
[Daycare Name]

Edit that to match what's true for you. Don't promise a timeline you can't back up.

Sending dogs home: set the rule before you need it

It helps to have a written illness policy. A reasonable version says that dogs showing a cough, nasal discharge, fever or lethargy go home right away and don't return until a vet clears them. Whether you ask for a vet note, a time period without symptoms, or both is up to you and your vet. Rules and advice differ, and your vet knows your dogs.

Applying it consistently matters more than the exact wording. If a regular's dog gets a pass and a new customer's doesn't, you'll pay for it in trust.

For a cluster, ask your vet whether you should pause group play, shut for a few days, or split dogs into smaller groups for a while. Closing costs money, and it is still often cheaper than a longer outbreak with dogs going home sick every day.

Consider contacting the owners of boarding dogs separately. A boarding dog who gets sick while the owner is away is a call you want to make early.

What about vaccines?

Many daycares require a bordetella vaccine, one of the vaccines that targets some of the causes of kennel cough. It does not cover every cause, and a vaccinated dog can still get sick. Say so when owners ask. Whether a dog needs an extra booster or a different form of the vaccine is a vet decision.

If you check vaccine dates at check-in, a lapsed bordetella date should stand out before the dog walks in. DogDaycareManager flags expired vaccines in red at check-in and emails owners 30 days before and on the day a shot expires, which helps with the paperwork side. It does nothing about an infection already in your room, though.

Keep records as you go

Write down what happened while it's fresh: the date, which dogs showed signs, which dogs were in contact, who you called, what the vet said, what you told owners, and when. It helps you spot patterns, answer questions later, and show your insurer or a local agency what you did if anyone asks.

A dog's notes field is a fine place to mention "sent home with cough, vet cleared on DATE." That way, the next person on the schedule sees it.

When it's over

An outbreak isn't over the moment the last cough stops. Ask your vet how long to wait before returning to normal. Then:

• Deep clean again, including bedding and anything porous.
• Tell owners you're reopening and what changed (a stricter illness rule, a more frequent cleaning schedule, a restriction on new dogs for a week).
• Look at the layout. Does everyone breathe the same air all day? Could a smaller group split help?
• Update your policy so the next time is faster.

Owners remember how you communicated more than the fact that it happened. A prompt, honest note builds more trust than silence, even when the news is bad.

Quick FAQ

Can I stay open? Maybe. That's a conversation for your vet, who knows how many dogs are affected and how they're housed.

Should I tell people the name of the dog that got sick? Generally no. Say "a dog," not whose.

Do I have to report it to anyone? It depends on where you are. Ask your local animal control office or state agriculture department whether anything is required for your facility.

Is it my fault? Probably not. Respiratory illness spreads through shared air, even in clean facilities. What you control is how quickly you respond.
