Heartworm disease can put your dog’s health at serious risk, and infected mosquitoes can be found across the United States. Give your dog a simple line of defense with Heartgard Plus for Dogs, a once-a-month, real-beef chew designed to help prevent heartworm disease.

More than heartworm prevention, Heartgard Plus also treats and controls three species of hookworms and two species of roundworms. Its tasty chew makes monthly protection easier to work into your dog’s routine, helping you stay on track with the parasite protection your furry family member needs.

Recommended For:

Puppies and Adult Dogs: Suitable for dogs from 6 weeks of age, when used as directed.
Dogs of Different Sizes: Available in weight-specific formulations for small, medium, and large dogs.

Important: Heartgard Plus is a prescription medication in the United States. Have your veterinarian test your dog for existing heartworm infection before starting prevention and confirm the appropriate product and dosage.

Heartgard Plus Coverage:

Heartgard Plus for Dogs provides monthly protection against heartworm disease while also treating and controlling common intestinal worms. Each monthly chew targets the following parasites:

Heartworms: Prevents canine heartworm disease by eliminating the tissue-stage larvae of Dirofilaria immitis for one month (30 days) after infection.
Roundworms: Treats and controls Toxocara canis and Toxascaris leonina.
Hookworms: Treats and controls Ancylostoma caninum, Uncinaria stenocephala, and Ancylostoma braziliense.

With one monthly chew, you can help protect your dog against heartworm disease while managing these specified intestinal parasites as part of your veterinarian-recommended prevention routine.

Directions

Giving Heartgard Plus for Dogs is simple when you follow the recommended monthly schedule.

Give One Chew Each Month: Administer the prescribed chewable orally once every month, using the strength appropriate for your dog’s weight.
Make Chew Time Easy: Offer it by hand or with a small amount of dog food. Encourage your dog to chew rather than swallow it whole. You can break it into pieces if your dog tends to swallow treats without chewing.
Make Sure Your Dog Gets the Full Dose: Watch your dog for a few minutes after administration to ensure the entire dose is swallowed and not rejected. If any portion may have been lost, the product label recommends redosing.
Keep Up With Monthly Prevention: Give each dose on schedule throughout the year, as directed by your veterinarian. Consistent monthly dosing is important for effective heartworm prevention.

Missed a Dose? Contact your veterinarian for guidance on restarting the monthly schedule, especially if multiple doses have been missed. Do not give extra doses without veterinary direction.

Storage Tip: Remove only one chewable from its foil-backed blister card at a time. Keep the remaining chewables in their original box to protect them from light.

How Does Heartgard Plus Work?

Heartgard Plus for Dogs combines two active ingredients, ivermectin and pyrantel, to provide monthly heartworm prevention and treatment and control of certain intestinal worms.

Ivermectin: Eliminates the tissue-stage larvae of Dirofilaria immitis, the parasite responsible for heartworm disease, helping prevent these larvae from developing into adult heartworms.
Pyrantel: Treats and controls specified intestinal roundworms and hookworms in dogs.

Together, these ingredients provide heartworm prevention alongside targeted protection against common intestinal worms when Heartgard Plus is administered monthly as directed.

5. Does Heartgard Plus Kill Adult Heartworms?

8. What Should I Do If I Miss a Heartgard Plus Dose?
