Overview
Kennel cough (infectious tracheobronchitis) is a highly contagious respiratory infection causing a distinctive honking cough. It spreads rapidly in places where dogs congregate — boarding facilities, dog parks, groomers. Most cases are mild and resolve in 1-2 weeks, but it can progress to pneumonia in puppies, seniors, or immunocompromised dogs. Vaccination reduces severity but doesn’t prevent all cases.
Symptoms to Watch For
- Persistent dry, honking cough
- Retching or gagging after coughing
- Runny nose and sneezing
- Mild lethargy
- Normal appetite in most cases
How Nutrition Helps
A strong immune system shortens recovery time and reduces severity. Adequate vitamin C, vitamin E, and zinc support immune response during infection. Warm, soft food is easier on an irritated throat. Ensuring good hydration helps thin mucus and soothe the airways. Honey (1/2 tsp for small dogs, 1 tsp for large) can soothe the throat.
How Activity Helps
Rest during active infection. Avoid exercise that triggers coughing fits. Use a harness instead of collar to avoid pressure on the irritated trachea.
Prevention Tips
- Vaccinate (Bordetella) before boarding or daycare
- Avoid dog parks during outbreaks
- Good ventilation in kennels and boarding facilities
- Isolate coughing dogs from other pets
- Support immune health with proper nutrition
