Maine Animal Health Officials Remind Owners to Vaccinate Their Animals

October 1, 2025

One visit to a veterinarian can help protect animals and human health.

AUGUSTA - The Maine Department of Agriculture, Conservation and Forestry (DACF) is reminding animal owners to talk with their veterinarians about vaccinations for pets and livestock. Vaccination helps protect animals against diseases transmitted by other animals and insects, such as mosquitoes, and plays a crucial role in safeguarding human health.

"While you should always work with your veterinarian to determine what is best for the health of your animals, ensuring your animals are fully vaccinated plays a critical role in preventing numerous diseases," said DACF Assistant State Veterinarian Dr. Rachael Fiske. Since diseases, such as rabies, affect both animals and people, vaccinating animals helps keep everyone healthy.

Biosecurity Resources for Animal Owners and Veterinarians:

Protecting the health of your pets, livestock, and community starts with strong biosecurity practices. DACF provides tools, guidance, and best practices to help prevent the spread of animal diseases. Visit Maine DACF Biosecurity Resources for practical steps you can take today.

Vaccinations Against Mosquito-Borne Illnesses in Horses

Horses are particularly vulnerable to mosquito-borne illnesses, such as West Nile virus (WNV) and eastern equine encephalitis (EEE), both of which have been detected in the state of Maine. EEE is particularly fatal. Vaccination against these diseases, along with tetanus, is an essential part of equine health care.

Rabies Vaccinations are Essential for Multiple Species

The rabies vaccine is required by Maine law for all dogs and cats, and it is strongly recommended for other animals such as ferrets, horses, and livestock. Rabies is almost always fatal and is carried by wildlife common in Maine, including raccoons, skunks, bats, and foxes. Vaccination is the most effective way to protect pets and livestock, reduce the risk of exposure for people, and safeguard public health. Safe and effective vaccines are readily available through licensed veterinarians.

Other Core Vaccines for Dogs and Cats

Dogs should also be vaccinated against serious diseases such as parvovirus, adenovirus, parainfluenza, and leptospirosis. Like rabies, leptospirosis can affect both animals and people and is carried by wildlife. Cats benefit from vaccines that protect against feline leukemia, panleukopenia, herpes virus, and calicivirus.

Parvovirus deserves special attention, as it most severely affects very young, unvaccinated puppies.

Because parvovirus spreads easily in areas where dogs gather, DACF recommends that dog owners take precautions. Puppies under six months of age, dogs that are not yet fully vaccinated, and adult dogs with immune-compromising conditions should avoid dog parks or other places where dogs of unknown vaccination and health status frequently gather until they are properly protected.

Protecting Rabbits from RHDV2

Domestic rabbits can now be vaccinated against rabbit hemorrhagic disease virus type 2 (RHDV2), an extremely contagious and fatal virus that affects only rabbits and hares. While RHDV2 has not been detected in Maine, the disease has been confirmed in other U.S. states and Canadian provinces. A U.S.-developed vaccine provides an important layer of protection for Maine's rabbits.

Protecting Animal and Human Health Starts with a Vet Visit

A single visit with your veterinarian can help determine which vaccinations are appropriate for your animals and ensure they are up to date. Vaccination is a simple, effective step that protects animal health, human health, and Maines agricultural and recreational communities.
