This is indeed the best heartworm preventive.

Works just like heartgard but saves me money. Been using it for 6 months now and no issues at all.

I’ve been using Heartgard for years. My vet swears by it, and my dog thinks it’s a treat. Win-win!

This is the perfect treatment for my pooch.

Works just as well as the branded version but more affordable. My vet approved it and I’m happy with the results.
