The HALTI was the world's first dog headcollar and is designed to stop dogs from pulling. It was invented in 1979 by Dr Roger Mugford and is approved and recommended by vets and canine professionals worldwide. It's unique patented design works by gently directing the dog’s head, steering him into the desired position, just as a headcollar works to steer a horse. Naturally following the contours of a dogs face and positioned well down the dog's nose, the HALTI gives you maximum steering power and control. The particular advantage of the HALTI is its unique on-off muzzle-closing effect: when the dog attempts to lunge forward or attack, his jaws are closed by the slip ring. When he is relaxed or friendly, he can pant easily. The soft material and careful design and construction ensures the HALTI is comfortable and in many dogs can create a pronounced calming effect. The HALTI makes training and behaviour modification of dogs practical and safe. It can be used in a number of ways: either as a passive means to simply stop dogs pulling or as an active training aid. Millions have been sold worldwide to grateful owners of pulling dogs. HALTI comes in six sizes and all HALTI's have a padded noseband for extra comfort.
