Is your dog barking excessively, whining and hiding? These behaviors are likely caused by fear and anxiety. ADAPTIL is a clinically proven, drug-free solution that helps your dog feel calmer. ADAPTIL Calm On-The-Go Collar provides “comforting messages” (dog appeasing pheromones) that helps dogs feel calm and relaxed in situations like loud noises (thunderstorms and fireworks), staying alone, traveling or other fearful situations. These odorless messages are only perceived by dogs and provide a strong signal of security and comfort. Cats and people are not affected.
