Puppy vaccinations are essential for protecting young dogs from various infectious diseases. Vaccines help the puppy's immune system recognize and fight off harmful viruses and bacteria. Common vaccines include those for distemper, parvovirus, and rabies. Puppies typically receive their first vaccinations between six to eight weeks of age, with follow-up doses given every few weeks until they are about 16 weeks old. Regular vaccinations not only safeguard the puppy's health but also contribute to community health by preventing the spread of diseases among pets.
