    I had to find an alternative to Heartgard as my dog refused to eat it even when covered in cheese or meat. She would just spit it out. This is a small pills and works when wrapped in cheese or meat. by on 10/03/2019
  • Great Product
    Very happy with this product. Even more happy with the NEW product, Interceptor PLUS, which is a heart worm preventative, PLUS controls round, hook, whip & tape worms. I have a breed that is sensitive to some of the ingredients in HWP and my dogs do fine on this, but as with ALL medications, please check with your Vet or do the proper testing to insure your dog can be given this product. by on 09/04/2019
