ProHeart 6 (moxidectin) is the only injection that provides 6 full months of continuous heartworm protection in a single dose and is for healthy dogs 6 months and up. There are many medications out there that treat and prevent various parasites in dogs, including pills, chewables and topically applied liquids. But remembering to give those products every month can be challenging, even for the most well-intentioned and caring dog owners. A missed or delayed dose could put your dog at risk for heartworm disease. That’s why ProHeart 6 may put your mind at ease. With one injection, you protect your dog continuously for the next 6 months. Just a simple trip to your veterinarian is all you’ll need to give your best friend extended protection from heartworm disease.
