Help your dog stay calm and relaxed every day with the Halcyon™-K9 Calming Collar, designed with clinically proven P.E.T. pheromone technology. This continuous-wear collar slowly releases a proprietary calming pheromone (2M2B), mimicking the natural comfort signal a mother dog gives her pups. Effective for up to 30 days, the collar addresses common anxiety-related behaviors like barking, restlessness, fear of loud noises, and separation stress. Water-resistant and easy to use, this collar is a safe, drug-free way to support dogs of all breeds and life stages.
