Sentry Good Behavior Stop That! Noise & Pheromone Spray for DogsTo modify destructive or aggressive behavior, this new product for dogs combines noise and a specially-developed pheromone mist. The pheromone in our Sentry Good Behavior Stop That! Noise & Pheromone Spray mimics a natural pheromone that almost immediately calms and refocuses pets to end their negative behavior by reducing their excitability. This spray also emits a hiss of air to interrupt undesirable behaviors in dogs. Unlike other noise-making products that are very temporary, the spray’s pheromone mist redirects the pet’s attention and behavior. The effect is longer lasting than noise alone and helps the pet not to re-engage in the negative behavior. Proven to stop unwanted behaviors such as: barking, jumping up, aggression, pulling on leash and more.
