That distinctive honking cough could be kennel cough. Here's what it is, how it spreads, and how to help your dog recover.
What kennel cough is
Kennel cough is a highly contagious respiratory infection, usually causing a distinctive dry, honking cough. It spreads easily where dogs gather — boarding kennels, daycare, dog parks, and grooming salons.

Symptoms to watch for
The hallmark is a persistent honking cough, sometimes ending in a gag or retch. Mild cases may include a runny nose or sneezing. Most dogs stay bright and eat well; severe or worsening cases need attention.
Home care and recovery
Most mild cases resolve in one to three weeks with rest. Use a harness instead of a collar to avoid irritating the throat, keep your dog calm and hydrated, and isolate them from other dogs while contagious.
When to see the vet
See your vet if your dog is very young, old, or has other health issues; if coughing is severe; or if you notice lethargy, poor appetite, or breathing trouble, which can signal pneumonia. Vaccination helps prevent it.
