Vaccines protect animals against contagious diseases that can cause serious and sometimes fatal diseases. Because of vaccines many Americans live without fear of terrible diseases such as polio, tuberculosis, and others. The same is true of our pets. Because rabies is a very fatal disease that people can get as well as animals, there is a law requiring that all pets be vaccinated against the rabies virus yearly or every three years if a vaccine approved for three years is used. There are many other diseases that are more commonplace in the environment that can cause harm to your pet such as distemper, parvovirus, hepatitis, parainfluenza, and bordetella. We recommend vaccinating your pet against these pets using the purest annual (not three year) vaccines available to both protect your pet and avoid potential reactions.
