Many people are unsure about how often their dog should get shots. The answer depends on several factors, including the age of your dog, their health status, and which vaccines they need.
Puppies need to be vaccinated more frequently than adult dogs because their immune systems are not yet fully developed. They typically receive a series of vaccinations every 2-4 weeks until they are 16 weeks old. After that, they will need booster shots every 1-3 years depending on the vaccine.
Adult dogs also need booster shots, but not as often as puppies. If your dog is healthy and up-to-date on their vaccinations, they will likely only need boosters every 3 years or so. However, if your dog is at risk for certain diseases (such as rabies), they may need to be vaccinated more often.
Talk to your veterinarian about which vaccines are right for your dog and how often they should be given. They will be able to create a vaccination schedule that meets your dog's needs based on their age, health status, and lifestyle.
