The gsp is an escape artist to boot. Works great for my lab who is 90lbs. My pug has yet to escape.

The underside is padded with breathable material. Even has padding for your hand. They play rough. We're using the ring on the back now, i sure hope it holds a little longer than the chest ring did.

This harness cannot be trusted to actually restrain your dog if there is any tension on the leash.

The harness material is very hard and stiff. It probably works for non * puppies but lasted less than 24hrs with mine.
