Sentry® Calming Collar for Dogs

Sentry Calming Collars are an easy-to-use solution to resolve behavior problems in dogs. Proven Good Behavior pheromone technology is used to stop stressful behaviors such as barking, chewing and inappropriate marking.

The Calming Collar has been discontinued but we highly recommend the Thundershirt™ for dog anxiety. Learn More

How does it Work?

SENTRY Calming Collars mimic the pheromone that the mother dog produces to calm and reassure her puppies. Dogs recognize these pheromones throughout life. It mimics the natural way to help dogs cope with new and fearful situations. The Lavender and Chamomile provide a soothing fragrance.

The SENTRY Calming Collar for dogs is proven to effectively modify behavioral problems in dogs that are due to stress, anxiety and phobias, such as travel, thunderstorms, fireworks and new social interactions. Each collar releases pheromones for up to 45 days.

The Calming Collar is a safe, effective first-line intervention, often eliminating the need for powerful prescription medications. It can be used without long term side effects, and is safe for dogs of all breeds and ages.

Directions for Use:

Place collar around dog's neck, adjust to fit dog's neck comfortably. The collar must be worn loosely to allow for growth of the dog and to permit the collar to move about the neck. Generally, a properly fitted collar is one that when fastened, will snugly slide over the dog's head. Leave 2 or 3 inches for extra adjustment. Cut off the excess portion of the collar.

When fresh collars are stretched out they may have a powder coating. The collar is designed to release powder when applied, which will activate the Pheromone Technology. This powder is primarily a carrier for the pheromone technology, and not the pheromone technology itself. This powder is not harmful to animals. Wash hands after placing the collar on the dog. The effects of one collar will last up to 45 days. Seal collar in plastic bag when not in use to prolong the life of the product.

CAUTION: Remove the collar before shampooing your dog and replace it after the dog's coat is completely dry. Do not use collar on dogs with skin lesions. SENTRY Calming Collar is not a pharmaceutical product.

Please note: The Calming Collar is non-returnable once it has been opened.
