It is normal after vaccinations for dogs to have a low-grade fever and muscle aches. Your doggie may eat less and sleep more 24-48 hours after. Rarely, dogs will have an allergic reaction, such as hives, swelling of the face, vomiting or diarrhea. Severe reactions, if untreated, can result in death. If your dog has any of the aforementioned symptoms, please take him to the nearest emergency clinic for immediate treatment. Notify your veterinarian so he can take steps to prevent a recurrence with your dog's future vaccinations.

Similar to measles in humans, distemper is a highly contagious disease that affects the gastrointestinal, respiratory and nervous systems. Most commonly found in unvaccinated puppies, symptoms include cough, vomiting, diarrhea and nasal and eye discharge. In more advanced cases, dogs display neurological issues such as seizures, and lack of coordination. Distemper is typically fatal.

Vaccinations not only protect your doggie against certain diseases, but they also protect other animals that come into contact with your dog. Typically vaccinations begin with a three set series given monthly beginning at eight weeks of age. Vaccinations are, however not without controversy, and veterinarians are changing vaccine protocols. It is best to check ask your veterinarian what their recommendation is and to understand their rationale.
