Logan Whistles were originally designed by the Logan Family in the UK for their working dogs. They were Harford Logan's 'secret weapon' in helping him communicate with his dogs to win seven National Championships. There is now a full range of Logan 'sheepdog' whistles available - brass, stainless steel, lightweight alloy and non-metallic Delrin - and the tones they can create are suitable for training all working dogs or as an excellent recall whistle for pets. They are especially effective as dogs like and react well to the tones. Each of us creates a different sound using the same whistle so your 'voice' is unique and easily recognised by your dog resulting in faster reactions as they know for sure that it is you that is asking them for a trained response. Guidelines on using the whistle are provided on purchase. All of our whistle, accessories and jewellery are our own unique designs and all crafted with care in the UK.
