TRI-HEART PLUS has been our go-to heartworm prevention for years. My dogs love the real-beef flavor and take the chewables without any fuss. The Green box for my 40 lb dog works perfectly and I’ve never had any issues.

The Blue box for dogs up to 25 lbs is perfect for my small terrier. Easy to give and very effective. I appreciate the 6-month supply – it makes staying on schedule simple and stress-free.

We use the Brown box for our large breed and it provides excellent protection. The chewables are palatable and the formula is reliable. Great value and peace of mind knowing our dog is protected from heartworm and intestinal parasites.
