The Halti Optifit is a versatile headcollar designed by Dr. Roger Mugford to provide an optimum fit and which guarantees to stop your dog pulling. Its unique design works by gently directing the dog's head, steering the dog from the front so the owner has full control. With a self-adjusting chin strap and unique, reflective cheek straps which follow the contours of a dogs face, the Optifit doesn't rise into the dogs eyes or slide down to his lips. Designed to fit dogs that other headcollars don't - from short nosed Boxers to long nosed Greyhounds, the Optifit provides maximum comfort and optimum fit no matter what shape or size of dog. It also includes a Halti® safety link which connects to the dog's collar for extra security.
