The Canny Collar is the no-pull headcollar that works differently from every other headcollar on the market — and that difference is everything. Where traditional headcollars apply pressure to the nose or muzzle, the Canny Collar works behind the head, which is more comfortable for the dog, more effective for the handler, and less likely to cause the resistance and distress that muzzle-based headcollars can produce. The result is a collar that gently guides your dog to walk calmly beside you without the confrontation — even the strongest pullers respond to the behind-the-head mechanism because it works with the dog's natural movement rather than against it. Works behind the head — not on the nose or muzzle; more comfortable and less confrontational than traditional headcollars Voted Best New Product — by the UK pet industry; trusted by trainers, behaviourists, and handlers across the country Effective on strong pullers — gently guides even the most determined pullers to walk calmly on lead Stress-free walks — no more embarrassment, frustration, or fear of being pulled over 7 sizes — 23cm to 58cm neck; covers every breed from small dogs to large breeds 4 colours — Black, Red, Blue, Purple; coordinates with the Canny lead range From £21.95. 4 colours: Black, Red, Blue, Purple. 7 sizes: 23-28cm (Size 1) to 53-58cm (Size 7).
