Note: Cat and dog box patterns are different; please select the appropriate pet product. Calming Collar for Dogs: This calming collar uses advanced pheromone technology that mimics the natural pheromones released by a mother dog. These pheromones are activated by body heat and help support a calm and relaxed state in dogs. Pheromones are naturally recognized by pets throughout their lives, offering a safe and effective way to help manage stress and anxiety. Long-Lasting Relief for Up to 60 Days: The calming collar begins working within one hour and continuously releases pheromones for up to 60 days, providing consistent support. The collar is waterproof, so it does not need to be removed during swimming or bathing. Helps Manage Stress-Related Behaviors: The calming collar may help reduce stress and fear associated with loud noises, travel, vet visits, thunderstorms, fireworks, separation, and other environmental stressors. It can help reduce undesirable behaviors such as excessive barking and chewing, supporting better adaptation to challenging situations. Product Tips: Each collar is individually packaged. If sensitive to odors, open the package and allow the collar to air in a well-ventilated area for one hour before use. We are committed to delivering high-quality products and customer satisfaction.
