Heartgard Plus Chewables are a monthly preventive treatment that protects dogs against heartworm disease (which can be deadly) and treats and controls roundworms and hookworms. The tasty chews are made with real beef so giving this heartworm medication is as easy as giving a treat.

Heartgard Plus prevents heartworm disease. It also treats and controls roundworms and hookworms.

Give Heartgard Plus chewables monthly as directed by your vet. They’re made from real beef and can be given as a treat, or added intact to a small amount of dog food. The chewable should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected. If it is suspected that any of the dose has been lost, redosing is recommended.

Dogs and puppies six weeks of age and older

Ivermectin, pyrantel

In clinical field trials with Heartgard Plus, vomiting or diarrhea within 24 hours of dosing was rarely observed (1.1% of administered doses). Other possible side effects include depression/lethargy, vomiting, loss of appetite, diarrhea, dilated pupils, abnormal gait, staggering, convulsions, and excessive drooling.

If you have questions about any side effects, reach out to your vet.
