Factors that influence how often a dog should be vaccinated against kennel cough include:
* Dog's age: Puppies require a different vaccination schedule than adult dogs.
* Dog's health: Certain health conditions may require more frequent vaccinations.
* Dog's lifestyle: Dogs that are frequently exposed to other dogs may require more frequent vaccinations.
* The specific vaccine used: Some vaccines provide longer-lasting immunity than others.
* Local prevalence of kennel cough: Vaccination frequency may be adjusted based on the risk of exposure in your area.
Your veterinarian can recommend the best vaccination schedule for your dog based on these factors.
