  • Sturdy handles that can be strapped down when not in use with a hook-and-loop strip (sizes Mini-Mini & Mini) or a rubber flap with popper (sizes 0 to 4)
  • Over 20 years in dog harness development


Controlled Lead Handling

We have optimized IDC® Powerharness to provide you maximum control while also providing maximum comfort for your dog.


The harnesses’ chest strap is parallel to the leash ring - allowing the pullback you give to be felt by your dog in the most efficient and safe manner. This means that you can hold back or stop your dog when you need to with less effort.


The wide chest strap and the optional IDC® Chest Pad help distribute the power over the chest for the proper comfort of your pet.


Expert Design No Matter Your Dog’s Size

If you’re buying a harness for a puppy, a fully grown dog, or for a smaller breed, the IDC® Powerharness is the smart choice.


The structure of the harness differs between sizes, ensuring the same level of comfort and control is provided no matter how big or small your dog.
