Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory illness that affects dogs of all ages. It is commonly spread in places where dogs congregate, such as kennels, dog parks, grooming facilities, and shelters. While kennel cough is usually not life-threatening, it can cause discomfort and lead to more severe complications in young puppies, elderly dogs, or those with weakened immune systems. Because our dogs matter, we keep our dogs vaccinated for kennel cough, along with their regular vaccinations.
Symptoms of Kennel Cough
The most common symptom of kennel cough is a persistent, dry, hacking, fourceful cough that may sound like a honking goose. Other symptoms include:
• Retching or gagging, sometimes bringing up foamy saliva
• Sneezing and a runny nose
• Watery eyes
• Loss of appetite (in severe cases)
• Lethargy or low energy
• Mild fever
In most cases, dogs remain active and alert despite the cough. However, if your dog shows severe symptoms such as difficulty breathing, a high fever, or extreme fatigue, you should contact your veterinarian immediately.
How Kennel Cough Spreads
Kennel cough is caused by a combination of viruses and bacteria, with Bordetella bronchiseptica being the most common bacterial culprit. It spreads through:
• Direct contact with infected dogs (such as playing or sharing water bowls)
• Airborne droplets from coughing or sneezing
• Contaminated surfaces like toys, food bowls, or kennel bedding
Because the illness is so contagious, outbreaks commonly occur in areas with multiple dogs in close quarters. If your dog frequents places like a dog park or are going to be using boarding kennel anytime soon, we would highly recomend that you vacinate your dog for kennel cough. Our experinace has been that a repuatable boarding kennel will require a record of vaciation before allowing you to board your dog. Remember this also protects you, as it ensures that other dogs using the same boarding kennel don't bring a sick dog into the facility.
Treatment for Kennel Cough
Mild Cases
Most cases of kennel cough resolve on their own within 1 to 3 weeks, and mild cases can be managed at home with:
• Rest and limited exercise to prevent excessive coughing
• A humidifier or steam therapy (such as bringing your dog into a steamy bathroom) to help soothe the throat
• Plenty of fluids to keep your dog hydrated
• Honey or warm water with honey to ease throat irritation (check with your vet first)
Veterinary Treatment
If your dog has a severe or prolonged case, a vet may prescribe:
• Cough suppressants to reduce irritation
• Antibiotics if a bacterial infection is suspected
• Anti-inflammatories to relieve discomfort
Dogs with weakened immune systems or pre-existing conditions may require more aggressive treatment.
Preventing Kennel Cough
While it’s impossible to eliminate all risk, you can reduce your dog’s chances of getting kennel cough by:
• Vaccinating your dog – The Bordetella vaccine is available as an injection, nasal spray, or oral dose. It’s recommended for dogs that frequently interact with other dogs.
• Avoiding high-risk areas during outbreaks, especially if your dog is very young, old, or has respiratory issues.
• Keeping your dog’s immune system strong with a healthy diet, regular exercise, and routine vet checkups.
Final Thoughts
Kennel cough is a common and generally mild illness, but it can be uncomfortable for your dog. Most cases clear up on their own with rest and supportive care, but if symptoms persist or worsen, consult your veterinarian. Prevention, through vaccination and good hygiene, is the best way to keep your dog safe from this contagious disease.
If you suspect your dog has kennel cough, consider keeping them away from other dogs until they recover to prevent further spread.
