Ask your veterinarian about the benefits of adding ProHeart 12 to your annual wellness visit.
With no monthly doses to remember, there are no gaps in protection for a full year. It’s so important to keep your dog protected. Just one missed dose of any heartworm preventative can result in heartworm disease, a potentially fatal condition.
Just one dose of ProHeart 12 provides protection for your dog all year long.
