Dr. Furman recommends yearly vaccines for the health and longevity of your pet. Vaccines have saved the lives of many pets. Before effective vaccines pets routinely died from Distemper, Hepatitis, Parvovirus, Leukemia, Rabies, and numerous other upper respiratory viruses. Current vaccine protocols protect our pets. Puppies and Kittens need additional protection during the critical time period of 6 to 20 weeks of age. A series of vaccines are given during this time period every 3 weeks until the puppy or kitten is completely immunized.
