I hate to be someone with a bad review. Our dog is 7 yrs old,& a lab /german shepard mix rescue. We have always used HeartGuard for heartwormsr, never missing a month. She tested postive in Sept. She went thru the 6 mo. treatment at $126 a month & will be retested in April. Our vet changed her preventive to something else at $146 a month now. He said there's new strain now of mosquitoes. Please check with your vet's. It didn't work for us anylonger.

Very good

we're very pleased with it,our vet gives the thumbs up after each exam, thank you

This product works great for my dog!

I’ve been using Heartgard for years now. Chaz has never had any adverse side effects. He’s always taken to it well. I have no regrets going with Heartgard and best of all, it aids in keeping my guy healthy. Shipping is great and he never runs out. Thanks PetBucket!
