Sentinel Spectrum

You can protect your dog against fleas, heartworms, and intestinal worms, including tapeworms, with Sentinel 3-in-1 protection. In fact, 97% of dogs accept beef and bacon chews straight from the hand.

With a tablet, your dog can swim or be washed after treatment without restrictions, and it won't rub off on your furniture.
