Fortunately, you can prevent distemper by vaccinating your dog. Puppies can get their first shots around 6 to 8 weeks of age. Before their last round of initial immunization is achieved, they should be kept away from environments or situations (like kennels or dog parks) in which they might come into contact with an infected dog. Vaccinations can also be administered within four days of a dog’s exposure to the virus. These shots should be boosted annually for the extent of your pet’s life.
