All dogs are vaccinated with a 5:1 vaccine which protects your dog from Canine Distemper-Adenovirus Type 2-Parainfluenza-Parvovirus Vaccine. They are also treated for intestinal worms. Additionally, they are usually given rabies shots and always spayed or neutered by our vet prior to placement. Dogs at "The Ranch" are tested for heartworms and treated, if positive. All are on heartworm preventative. Shelter dogs that we post have not been tested for heartworms.
