EFFICIENT POWER TRANSFER - EFFECTIVE CONTROL The chest strap of the harness is parallel to the leash you hold in your hand and can therefore transfer power from you in the most efficient way. This means that you can hold your dog back or stop him when you need to, with less effort. The wide chest strap and optional chest pad help distribute the force across the chest, providing great comfort for your dog. SPECIFIC DESIGN - FOR EACH DOG SIZE To ensure the same comfort for all dogs, the harness structure is different for small and large dogs, the design is adapted to the specific dog sizes and relevant angles on the leash. The IDC harness consists of four layers. Under the water-repellent and comfort-enhancing outer layer is a flexible foam, a stiffening layer and a breathable OEKO-TEX certified lining. It is important to measure your dog carefully to choose the right harness size. Place four fingers behind the front legs to determine where the chest (girth) should be measured for harness sizes 0, 1, 2, 3 and 4, three fingers for Mini-mini and Mini sizes and two fingers for Baby 1 and Baby 2 sizes. The chest circumference should be measured where the strap will sit. Choosing the right size ensures maximum freedom of movement and protects the dog's neck and shoulders.
