Treating heartworm disease is costly and complicated.1 But prevention is simple. Trust #1 vet-recommended HEARTGARD® Plus (ivermectin/pyrantel) to prevent heartworm disease before it starts.2

Puppies Need Protection Too

Cuteness is no defense against heartworm disease. The American Heartworm Society recommends that puppies get started on a heartworm disease preventive as early as the product label allows.5 And because you need a prescription from your vet for a heartworm disease preventive, talk to them about HEARTGARD Plus—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 protection. That’s because the threat of heartworm disease doesn’t stop with dropping temperatures.3 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.6 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.

Three Tips for Preventing Heartworm Disease

Reduce Mosquito Exposure

Avoid bites to reduce risk. Eliminate standing water where mosquitoes can breed, avoid known mosquito habitats, and limit outdoor exposure during peak mosquito feeding times (dawn and dusk).

Use Preventive Medicine Year-Round

Monthly administration of a preventive, like HEARTGARD Plus, safely and effectively prevents heartworm disease by eliminating heartworm larvae before they can grow into dangerous adult heartworms.

Get Your Dog Tested Every Year

Before getting a prescription for a heartworm disease preventive, your dog must be tested for heartworms. Talk to your vet about testing options.

Hookworms and Roundworms Are Unexpected Threats

Your dog can get hookworms and roundworms by stepping in contaminated soil at the park or ingesting them in your own backyard. Luckily, HEARTGARD Plus treats and controls three species of hookworms and two species of roundworms.
