Heart worms can be detected through a blood test that can be done at a veterinarian’s office. Heart worms are transmitted by mosquitoes...a mosquito harboring a life stage of the heartworm will transmit it to a dog by biting it. It is not passed from dog to dog through casual contact. Heartworm disease is easily prevented, so if your veterinarian can test your dog and he is negative....there are a number of heartworm preventative products available through your veterinarian.
