The Coachi Professional Whistle is a lightweight whistle which allows you to adjust the pitch, to suit your dog's sensitivity or change the tone for different dogs, perfect for dog trainers and professionals. It is easy to change the pitch on the Professional Whistle, simply separate the 2 parts of the whistle, rotate the nut to adjust pitch and secure both parts back together. Whistles are great for recall training as they help to standardise commands and are great if different people are training or walking the same dog. Super-light and compact in design, the Professional Whistle can easily be slipped in a pocket or treat bag to ensure you always have it to hand. The attractive corded lanyard is fully adjustable so you can secure at the desired length and it is reflective too! The Coachi range was created by the experts at Company of Animals and it is designed to focus on promoting effective, humane and positive methods, making training simple and rewarding for both owners and their dogs.
