Halti Optifit Headcollar STOPS PULLING: the Halti Optifit Headcollar prevents pulling on the lead by gently steering and guiding your dog's direction. CUSTOMISABLE FIT: the Halti Optifit Headcollar has an adjustable nose band and cheek straps, secured with a camlock, to fit most dogs that do not fit standard-sized headcollars. KIND & HUMANE: made from strong but lightweight webbing, the Halti Optifit Headcollar is designed for comfort with a padded nose band and won't interfere with panting, eating or drinking. REFLECTIVE & SAFE: every Halti Optifit Headcollar has reflective cheek straps for improved visibility in low light and a safety link that attaches to your dog's collar, for complete peace of mind. BETTER TOGETHER: to get the best no-pull training experience, use the Halti Optifit Headcollar with our double-clip Halti Training Lead.
