Sentry HC Good Behavior Pheromone Dog Collar, 23-Inch

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.

1. Take the collar out of the packaging and stretch to full length. The tabs that held the collar in place should fall off when stretching; pull on any remaining tabs to remove them. 2. Bend the buckle in half between the holes in the buckle, so that you can easily pass the end of the collar through both holes. 3. Place the collar around your pet’s neck. Feed the collar through both holes, notches facing out. Fit to the neck of the dog. 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, and two fingers can be placed between the collar and pet’s neck. Leave 2 or 3 extra inches for collar adjustment, cut off remaining excess collar and dispose of in the trash. 4. Wash hands after placing collar on pet. Seal collar in plastic bag when not in use to prolong effectiveness.
