Kennel cough treatment will vary depending upon the severity of the illness in your dog.
Most cases are mild and generally clear up and go away on their own.
However, a bordetella vaccine will help to lessen the symptoms and the severity, even if your Golden Retriever has already contracted this virus.
When one of our Goldens developed this, it progressed to him needing additional care and the first thing my vet did, was to give him an intranasal bordetella vaccine to help reduce the severity.
Antibiotics may be needed if it progresses to a secondary bacterial infection.
The best treatment for kennel cough is to allow your dog to rest, and don't encourage a lot of play, as this will just set off her coughing fits.
Make sure she has plenty of water available to her, and if she doesn't appear to be getting better, or if she becomes worse, then schedule an appointment with your vet.
You will want to take extra precautions if you have any puppies in the house, as their young, immature immune systems may not be able to fight off the virus, as well as adult dogs can.
