Description How does it work: Mother dogs communicate with their puppies using natural “comforting messages” released from the mammary zone. These “comforting messages“ are scientifically called Dog Appeasing Pheromones. They are odourless and are only perceived by dogs. These “comforting messages” provide a strong signal of comfort and security to the puppies. The Topdog Training Calming Collar helps puppies & dogs feel as comfortable and secure with their new family as they did with their mother. How fast will I see results: Many dog owners start to see results within the first 7 days.  However, every dog is unique. Depending on how long the signs have been present and how severe the signs may be, it may take longer to see an improvement. We recommend using The Topdog Training Calming Collar for at least 1 month. How long should I use it?: Most of the dogs will benefit from a permanent use of The Topdog Training Calming Collar to create a reassuring environment at home and even outdoors. The minimum recommended duration is one month. When to use: To comfort your dog constantly at home and outdoors If your dog is scared of loud noises like fireworks or thunderstorms If your dog has issues when staying in a kennel (barking, whining, pacing…) If your dog shows signs of fear when on walks If your dog has issues with training When not to use: If your dog’s issues are not related to stress. If your dog’s issues are due to a lack of stimulation in the environment. If your dog is soiling the house due to lack of toilet training, or due to medical reasons.  It is important to consult a veterinarian to rule out potential medical issues.
