The Fetch accessory allows you to attach your GoPro to your dog. You might be wondering ‘but what if my dog is too big/small for the harness?’. No worries because the harness can adjust the size to any dog. The GoPro would sit attached to the top of the dog and or the bottom. These two angles are up to you. A good tip is to strap the harness to the dog tight so the camera is snug and you will have more footage that is stable. But you don’t want the harness to be so tight that the dog is uncomfortable or can’t breathe.
