Heartgard Plus Chewables for Small Dogs Up to 25 lbs (Blue)

Heartgard Plus Chewables for Small Dogs Up to 25 lbs (Blue) are formulated to help prevent heartworm disease while treating and controlling certain hookworms and roundworms. Designed specifically for small dogs weighing up to 25 pounds, this blue pack monthly chew provides targeted dosing with 68 mcg of ivermectin and 57 mcg of pyrantel per chewable tablet. Suitable for small dogs and puppies 6 weeks of age and older, it offers reliable parasite protection in an easy-to-administer, real beef-flavored chew. Given once every month as directed, this weight-specific formula supports consistent, year-round heartworm prevention and intestinal worm control for small dogs.

How It Helps

Heartgard Plus contains two trusted active ingredients, ivermectin and pyrantel that work together to protect your dog. It helps prevent heartworm disease by eliminating the early stage of the parasite before it can develop into adult heartworms. It also treats and controls certain species of hookworms and roundworms that can affect your dog’s digestive health. Given monthly, it provides continuous protection when used as directed by your veterinarian.

Who It’s For

Small dogs and puppies 6 weeks of age and older, weighing between 0-25 lbs.

Your veterinarian can help determine the correct strength based on your dog’s current weight.
