Canine vaccinations are essential for protecting dogs from various infectious diseases. Vaccines work by stimulating the dog's immune system to recognize and fight off specific pathogens, such as parvovirus, distemper, and rabies. Regular vaccinations help ensure that dogs remain healthy and can prevent the spread of diseases to other animals and humans. Puppies typically receive a series of vaccinations starting at around six to eight weeks of age, followed by booster shots as they grow. It's important for dog owners to consult with a veterinarian to determine the appropriate vaccination schedule and to keep their pets up to date on necessary shots for optimal health.
