For more than a decade, SENTRY has worked side by side with leading pet experts and top universities researching effective ways to help pets lead happier, less stressful lives and to strengthen their bonds with their owners. Dogs and puppies can't talk, so the way they show they are scared, frustrated, or not feeling well is to change their behavior like excessive barking, destructive chewing, and marking inside your home.  SENTRY Calming Diffuser Refill for Dogs quickly releases a pheromone into your home to help calm and alleviate unwanted behaviors. Replace diffuser bottle every 30 days for maximum effectiveness. Good behavior is right around the corner with SENTRY in-home calming products.
