Dogs' recommended vaccination and treatment schedule varies depending on age, lifestyle, health status, and geographic location. However, some essential vaccinations and treatments are typically recommended for all dogs.   Puppies: Most puppies should receive a series of three core vaccinations, starting at 6-8 weeks of age. This includes a Distemper/Parvo combination vaccine, a Rabies vaccine, and a Bordetella (Kennel Cough) vaccine. Depending on the area in which you live, your veterinarian may also recommend additional vaccines such as Leptospirosis or Lyme Disease. Adult Dogs: The recommended vaccination and treatment schedule for adult dogs is an individualized plan that should be determined by a veterinarian based on your dog's specific needs. Generally, adult dogs should receive booster shots of core vaccines every 1-3 years, depending on the vaccine and your dog's lifestyle. Core vaccines include rabies, distemper, parvovirus, and adenovirus. Non-core vaccines may be recommended depending on your dog's lifestyle and geographic location. These include vaccines for Bordetella, Lyme disease, Leptospirosis, and Canine Influenza Virus. Elderly Dogs: elderly dogs should receive annual vaccines for distemper, parvovirus, parainfluenza, and rabies. They should also be tested for heartworm and other parasites every year. Additionally, elderly dogs should receive regular exams from a veterinarian to monitor changes in health and identify any potential issues earlier.
