Heartworm disease can be a fatal but preventable condition that is transmitted by mosquitoes. We highly recommend using a heartworm preventative year-round throughout your pet’s life. There are quite a few heartworm preventatives (both oral and topical) available. Some just prevent heartworms, some have intestinal parasite control and some offer flea control as well. We’d be happy to discuss your options with you and find the right product for you and your pet.
