🫁 What is kennel cough?

“Kennel cough” is the familiar name for canine infectious respiratory disease complex (CIRDC) — a group of contagious infections that affect a dog’s nose, throat and airways.

It is not caused by one single germ. Several viruses and bacteria can be involved, sometimes at the same time. Common contributors include Bordetella bronchiseptica, canine parainfluenza virus and canine adenovirus type 2, although other organisms may also play a role.

Dogs can pick up CIRDC through close contact with other dogs, coughing or sneezing droplets, or shared items such as bowls, toys and bedding. Boarding kennels, daycare, training classes and grooming salons can all increase exposure opportunities.

A dog may be contagious before it looks obviously unwell, which is why separating coughing dogs and following a facility’s health policies are important.

A cough does not automatically mean kennel cough. Heart disease, airway problems and other illnesses can also cause coughing, so a veterinary examination may be needed to find the cause.

👀 Signs to watch for — and when to call us

The most recognisable sign is a sudden, frequent, dry or “honking” cough. Some dogs gag or retch after coughing, sometimes producing frothy fluid that can look like vomit. Sneezing, a runny nose or watery eyes may also occur.

Signs vary from dog to dog, and coughing can have many different causes. Contact our clinic if your dog has:

• A cough that persists, worsens or keeps returning

• Low energy, reduced appetite or fever

• Nasal discharge, sneezing or eye discharge

• A cough severe enough to cause vomiting or distress

Seek urgent veterinary care if your dog has difficulty breathing, unusually rapid breathing, marked weakness, collapse, blue or pale gums, or rapidly worsening signs. Puppies, senior dogs and dogs with existing health conditions may need earlier assessment.

If your dog is coughing, please phone us before coming in. We can advise the safest way to bring your dog to the clinic while minimising contact with other patients.

🐾 Which dogs may need extra care?

Dogs of any age or breed can be exposed to CIRDC. However, puppies, senior dogs and dogs with weakened immune systems or existing health conditions may be more likely to develop complications.

Flat-faced (brachycephalic) breeds, such as French Bulldogs, Pugs and Boston Terriers, can have narrower or less efficient airways. Any change in their breathing should be taken seriously — please ask us what warning signs to look for.

Dogs that regularly attend boarding, daycare, grooming, training or other busy group settings have more opportunities to encounter respiratory infections. This does not mean every dog will become ill, but it is sensible to check vaccination requirements, cleaning practices and sick-dog policies before booking.

🛡️ Prevention: practical steps for Hong Kong’s climate

Ask our veterinary team which vaccinations are appropriate for your dog, particularly before boarding, daycare or regular group activities. Vaccines can protect against selected CIRDC organisms and may reduce the likelihood or severity of illness, but no vaccine covers every possible cause or guarantees complete protection.

You can also reduce risk by:

• Keeping bowls, toys, bedding and grooming equipment clean

• Avoiding shared communal items where practical

• Choosing well-ventilated spaces and asking facilities about cleaning and illness policies

• Keeping your dog away from obviously unwell dogs

• Keeping a coughing dog at home and away from other dogs until advised otherwise

• Checking boarding or daycare entry requirements well before your booking

• Considering less crowded indoor gatherings during wet or cool weather if respiratory illness has been reported locally

Weather alone does not determine whether kennel cough is circulating, but good ventilation, lower crowding and sensible hygiene can help reduce avoidable exposure. These measures lower risk — they cannot remove it completely.

🏠 Home care: what to do — and what to avoid

If your dog has mild signs, contact us for advice and keep them comfortable, rested and separated from other dogs while you wait.

• Offer fresh water and a calm, warm place to rest

• Avoid strenuous exercise, excitement and anything that triggers coughing

• Note when the cough started, how often it occurs, and any changes in breathing, energy or appetite

• Use a harness rather than a collar if pulling on the lead worsens the cough

Do not give human cough or cold medicines, leftover antibiotics, or any other medication unless specifically directed by your veterinarian. Many human medicines can be unsafe for dogs, and the right treatment depends on the cause and severity of illness.

Do not assume a cough is harmless or try to diagnose it at home. A veterinary consultation helps determine whether simple supportive care is enough, or whether examination, testing or further treatment is needed.

🩺 How our veterinary team can help

A consultation allows us to examine your dog, discuss possible causes and recommend appropriate next steps. Depending on your dog’s signs and history, we may advise monitoring, diagnostic tests, treatment, or further assessment.

We can also review your dog’s vaccination schedule and help you prepare for boarding, daycare, grooming or travel. If your dog is coughing, please call ahead so we can guide you on arrival and protect other patients.

❓ Quick FAQs

Can my dog catch kennel cough without going to a kennel?

Yes. Dogs can be exposed wherever they meet other dogs or share air, bowls, toys or bedding — including parks, daycare, grooming salons and training classes.

Does vaccination prevent every case?

No. Vaccines target selected organisms and can reduce the risk or severity of illness, but they do not protect against every cause of CIRDC. Ask us which vaccines suit your dog’s lifestyle.

Should I wait and see if a cough improves?

Contact us if the cough persists, worsens or is accompanied by low energy, reduced appetite or fever. Breathing difficulty, collapse or rapidly worsening signs need urgent care.

Can my dog return to daycare once the cough stops?

Please ask us and check the facility’s policy. The safe return date depends on the diagnosis, recovery progress and the facility’s infection-control requirements.

💚 A calm plan starts with a conversation

A cough can have several causes, and early advice can make caring for your dog much simpler. Before the weather changes or your next boarding or daycare visit, speak with our team about vaccination, health checks and practical precautions.
