Rabies is a viral disease that causes inflammation of the brain in all mammals. Humans and animals can become infected through the bite of an infected animal. Rabies is endemic in wildlife such as bats, raccoons, and foxes. While these animals do transmit the disease, dogs, cats, and even horses can become infected through the bite of wild animals and then pass it to their human caregivers. Caring for your horse daily allows you to learn the attitude, behavior, and demeanor of your horse.
