Adaptil™ (Formerly D.A.P®) - Dog Appeasing Pheromone (D.A.P.) reduces or prevents stress-related behavior. Female dogs secrete pheromones that comfort and reassure their nursing puppies. These "appeasement" pheromones have the same calming effect on adult dogs. D.A.P. mimics these appeasement pheromones to reduce or eliminate stress in dogs of all ages. The plug-in diffuser allows the scent to permeate throughout the environment. The scent calms dogs during thunderstorms, fireworks, visits by strangers, or moving to a new home. It also helps puppies adapt to new environments.
