It's supposed to be a walk, not a drag or a chase or a pull or a tug of war, so get your pooch fastened into the PetSafe Easy Walk Harness and show them how it's supposed to work. This simple harness discourages pulling by putting the stress across their shoulders instead of against their throat. Choose from the selection of sizes and colors to find the one that's just right. Made of nylon. Quick snap buckle for easy on and off. 4 adjustment points provide comfort and reliable fit. Martingale loop in chest piece prevents twisting. Choose from the available color and size options.
