Sentry Calming Collars use patented good Behavior pheromone technology. Using a pheromone that mimics the one mother dogs produce to calm their puppies, the collars are clinically proven to reduce or eliminate stress-related behavior such as inappropriate marking, excessive barking and chewing. Collars help alleviate problem behaviors triggered by travel, thunderstorms, fireworks, being left alone and new social situations. This collar continues to release calming pheromones for your dog for 30 days. It can be used for dogs of all ages and breeds without long-term side effects.
Place collar around dog's neck, adjust to fit comfortably. The collar must be worn loosely to allow for growth of the pet and to permit the collar to move about the neck. Generally, a properly fitted collar is one that when fastened, will snugly slide over pet's head. Leave 2-3" for extra adjustment. Cut off the excess portion of the collar. The collar is designed to release powder when applied, which will activate the pheromones. When fresh collars are stretched out they may have a powder coating. This powder is primarily a carrier for the pheromone technology and not the pheromone itself. This powder is not harmful to animals. Wash hands after placing collar on pet. The effects of one collar last up to 30 days. Seal collar in plastic bag when not in use to prolong the effect. Caution: Remove the collar before shampooing your dog and replace it after the coat is dry. Do not use collar on dogs with extensive skin lesions. Sentry Calming Collar for Dogs is not a pharmaceutical product.
