Sentry Understands Anxious Pets Sentry uses pheromone technology to effectively change your pet’s behavior. With the help of their products, good behavior is right around the corner.

Change the Behavior, Not the Pet
Pets can’t talk, so they show they’re scared, frustrated, or not feeling well by changing their behavior. Give them the help they need for excessive barking or meowing, jumping on guests, licking, scratching, and spraying with the Sentry line of behavior products.
