What is ProHeart 6? ProHeart 6 is the only single dose injection that can protect your dog from heartworm infection continuously for 6 months. With ProHeart 6, a simple trip to your veterinarian is all you'll need to give your best friend extended protection from heartworm disease!

                          Across the United States, dog owners inconsistently administer heartworm preventatives, putting their dogs at risk. Only 17% to 38% of dogs under veterinary care received heartworm preventative prescriptions,1 and 49% of dog owners are not current with heartworm prevention.2
