Talk to your veterinarian about the heartworm testing that is recommended before starting your dog on a heartworm prevention program.
Some intestinal parasites, such as roundworms and hookworms, can be spread to people.
Talk to your veterinarian about other measures you can take to protect yourself and prevent your pet from being infected or re-infected with intestinal worms.
Notify your veterinarian of any other medications or supplements your dog is taking, and also if your dog has had any reactions to previous medications.
