Tri-Heart Plus is an easy-to-feed chewable tablet prescribed to help keep your dog free of heartworm and other dangerous parasites. When given monthly, this simple and palatable tablet helps to protect your pet by killing the larvae before they reach your dog's heart. Best of all, the tasty tablets can be fed just like a treat! Your pet won't even know you're working to protect their heart.


Tri-Heart Plus is a monthly chew indicated to kill heartworm larvae and to control/treat adult hookworms and roundworms.

Possible Side Effects

Tri-Heart Plus is safe and has caused no side-effects in most dogs, but upset stomachs have been reported. Incoordination, convulsions, or drooling have also been reported rarely. Always contact your veterinarian if your pet appears sick or behaves strangely after taking Tri-Heart Plus.

Drug & Food Interactions

Talk to your veterinarian about any other drugs your dog is taking before starting Tri-Heart Plus.


All dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart Plus, which is not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program. Tri-Heart Plus is not indicated for dogs younger than 6 weeks old. Herding breeds (such as Collies) can be sensitive to the active ingredient, so talk to your veterinarian if your dog may be affected. If you miss a dose, your dog needs a blood test to resume your normal doses safely. Notify your veterinarian if you've skipped a dose or have any concerns. Keep this and all drugs out of the reach of children.
