    Best in the market

    I’ve used heartgard plus for years with my pets and it’s protected them well. No complaints here and will continue to use sierra for my pet’s meds. Just wish it wasn’t too pricey and yet it’s the lowest around. I can’t complain too much with the world affecting companies today so I still appreciate this site and everything they have.

    Heartgard Plus

    Posted by Flash on Feb 01, 2026

    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.
