The chewables should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that no part of the dose is lost or rejected. If it is suspected that any of the dose has been lost, redosing is recommended.

  • So easy to give every month!

    By on

    This is by far the favorite heartworm prevention my dog doesn't have a problem taking. It's a chew which makes it easier, it has a beefy smell, and it covers a fairly large spectrum of parasites without that cost. From heartworm, intestinal parasites including: hookworm, roundworm, whipworm and those pesky tapeworms. It is one of the few out there that covers those tapeworms from time to time. It's at a such affordable price as well.
