Michigan requires dogs to be vaccinated against rabies, which is the only vaccine legally mandated by state law. This vaccination is essential for public health and safety, as rabies is a fatal disease transmissible to humans. Dogs must receive their first rabies vaccination by a licensed veterinarian, typically at 12-16 weeks of age, followed by a booster at one year, and then every one to three years depending on the vaccine type used.
While rabies is the only legally required vaccine in Michigan, veterinarians strongly recommend several other vaccines as part of a standard preventive care protocol. The core vaccines typically advised include DHPP (protecting against distemper, hepatitis, parvovirus, and parainfluenza) and leptospirosis. Non-core vaccines may be recommended based on your dog's lifestyle and risk factors, such as those for Lyme disease, Bordetella (kennel cough), and canine influenza.
Puppies require a series of vaccinations starting at 6-8 weeks of age, with boosters given every 3-4 weeks until 16 weeks old. Adult dogs need regular boosters to maintain immunity. The specific vaccination schedule and which non-core vaccines are appropriate should be determined by your veterinarian, who can assess your individual dog's risk factors and health status. If your dog will be traveling, boarding, or participating in dog shows or parks, additional vaccines may be prudent regardless of legal requirements.
