Dog vaccination is a crucial part of pet care that helps protect dogs from various infectious diseases. Vaccines work by stimulating the dog's immune system to recognize and fight off specific pathogens, such as canine parvovirus and distemper. Regular vaccinations can prevent serious health issues and are often required for boarding or grooming services. Puppies typically receive their first vaccinations between six to eight weeks of age, followed by booster shots as they grow. It's essential for dog owners to consult with a veterinarian to create a vaccination schedule tailored to their dog's needs, ensuring optimal health and protection throughout their life.
