As a puppy, your dog receives a certain amount of protection from disease while nursing his mother’s milk. However, soon enough your dog will need vaccinations to keep him from contracting dangerous diseases if he is exposed to them. Some communities require certain vaccinations by law so check with your animal control organization to understand your responsibilities. Other vaccinations are recommended based on your dog’s specific activities. Vaccinations may be given as a single shot or they may need to occur in a series of shots. All vaccinations will require periodic booster shots to ensure continued protection from disease. Don’t skip shots in a series or boosters or you could put your dog at risk for disease. He may be cranky after receiving a vaccination and may be sore at the injection site. Contact your Pleasanton, CA vet to learn more and to set up a comprehensive vaccination schedule.
