The Halti OptiFit Headcollar is a must for medium to large dogs that pull on the leash. This dog headcollar stops pulling without putting pressure on necks allowing for full range of motion & control. For better no-pull walking and training, we've paired the Optifit with our bestselling Halti Training Leash. This dual clip leash attaches to your dog's headcollar and walking collar for improved control, comfort and training. Unlike traditional no pull dog headcollars, the OptiFit is designed to fit a wide range of noses regardless of breed or muzzle size providing a no pull headcollar solution to wide variety of dogs and breeds. The Halti OptiFit Headcollar is made with a padded noseband so the headcollar stays in place while in use. The dual-clip leash also provides flexibility to connect to your dog's Headcollar and walking leash for improved security.
