The Halti Headcollar is a dog training aid designed to address pulling on the lead. Developed by animal behaviourist Dr Roger Mugford — the original designer of the headcollar concept — it works on the principle that guiding the head redirects the whole body. Fits dogs of all breeds and sizes.

The headcollar attaches around the muzzle and behind the ears, with the lead clipping at the chin. This shifts the point of control to the dog's head rather than the neck, which makes pulling mechanically harder — the dog steers where its nose points. It provides maximum control for strong and persistent pullers without using force or discomfort to achieve it.

A straightforward solution for owners dealing with dogs that have outpulled conventional collars or harnesses. The Halti addresses pulling through geometry rather than restriction, which is why it holds up with large, powerful breeds where other training aids stall.
