    I've been using Heartgard Plus exclusively for many years to prevent heartworm in my dogs, none of whom have ever been diagnosed with the problem. No flag, no foul.

    In well over 30 years it has almost always worked. I've only encountered a problem once.

    I shop at Sierrapetmeds because I love my dog. I know I can trust them to provide quality products at low prices. I have been shopping here for years and I have never been disappointed.
