If you’ve just bought a puppy, you surely know the importance of having your pup vaccinated, but do you understand how vaccines work?

Vaccines contain the same bacteria or viruses that cause the disease you want to prevent, but they have been chemically modified so that they don’t cause any harm. Instead, the vaccine causes your dog to produce antibodies that fight the harmful bacteria. Thus, if your dog is exposed to the disease in the future, the antibodies will destroy the viruses or bacteria.
