Clients Thought
Dog owners across the country have made Heartgard Plus Chews part of their monthly routine — here’s what some of them have to say.
I was skeptical at first about how well a chew could actually work, but after my vet explained how it protects against heartworm and intestinal parasites all in one, I gave it a try. That was two years ago and my dog hasn’t had a single issue since. Simple, effective, and my dog loves the taste.

My golden retriever has been on Heartgard Plus for three years now and I wouldn’t switch to anything else. She actually gets excited when she sees the chew coming — no hiding it in peanut butter or fighting to get her to take it. My vet recommended it from day one and I’m glad I listened.

Honestly, I was just looking for something simple that actually worked. Heartgard Plus checks both boxes. My dog thinks it’s a treat, I give it once a month, and we’re done. No stress, no struggle — just reliable protection that fits into a busy schedule.
