Kennel Cough

Also called: Canine infectious respiratory disease complex, CIRDC, infectious tracheobronchitis, canine cough

• Dogs
• Infectious (viral)
• Any

A highly contagious syndrome caused by several bacteria and viruses — including Bordetella bronchiseptica, canine parainfluenza virus, and canine adenovirus type 2 — often more than one at once. Signs are frequently mild and self-limiting but can progress in some dogs.

Signs to look for

• Sudden, frequent, honking cough
• Often begins 5–10 days after contact with other dogs
• Sometimes sneezing or nasal/eye discharge
• Usually the dog is otherwise well

How a vet diagnoses it

Commonly diagnosed on a history of exposure plus typical signs; respiratory PCR panels can identify specific pathogens where needed.

Treatment

Often supportive care and rest; antibiotics if bacterial involvement is suspected. Affected dogs should be isolated from other dogs while coughing.

Monitoring at home

Usually resolves with time. Watch for worsening — lethargy, poor appetite, or breathing difficulty may signal pneumonia and need prompt care.

Who tends to get it

All breeds and ages; puppies and dogs in group settings (boarding, shelters, daycare, shows) are at particular risk. Vaccines against several agents are available and often required by boarding facilities.
