Heartworm Disease Prevention

For heartworm disease prevention, trust #1 vet-recommended HEARTGARD® Plus (ivermectin/pyrantel).1

Heartworm Disease: Potentially Deadly; Prevention is Easy

Just one bite from an infected mosquito could put your pet at risk for heartworm disease—a serious condition that can cause permanent damage even before it can be diagnosed. Left untreated, heartworm disease can cause heart failure and even death. Treating heartworm disease is costly and complicated.2 But heartworm prevention for dogs is simple. HEARTGARD Plus chews prevent heartworm disease and treat and control five species of intestinal worms. Plus, dogs love HEARTGARD Plus: they’re #1 dog-preferred and made with real beef.3,4

Puppies Need Protection Too

Cuteness is no defense against heartworm disease. The American Heartworm Society recommends that heartworm prevention for puppies starts no later than 8 weeks of age.5 And because you need a prescription from your vet for a heartworm disease preventive, talk to them about HEARTGARD® Plus (ivermectin/pyrantel)—the real-beef chew that’s safe for puppies as young as 6 weeks of age with no minimum weight requirement.

Year-Round Protection Is Essential

The American Heartworm Society recommends giving your dog year-round prevention.5 That’s because the threat of heartworm disease doesn’t stop with dropping temperatures.5 Many pet owners might assume that they only need to give their dog heartworm disease preventives when it’s warm. While heartworm transmission can decrease in winter months, the risk never reaches zero.7 What’s more, on-again, off-again heartworm disease protection is unreliable and can leave your dog with gaps in protection that make him vulnerable to heartworm disease.
