Sentinel® prevents whipworms, adult roundworms, adult hookworms, and fleas from infesting your dog.

This prescription preventative breaks the flea life cycle by halting the maturation of flea eggs and can even be taken in conjunction with Capstar for a more thorough treatment. These tabs are also beef-flavored to make monthly administration simple and easy.
