Our dog tack area is a sea of Tuenne product as we have various colors lengths etc. With our Newfoundlands we have destroyed many leashes and all of our Tuenne products are like new, work great and are strong enough for our dogs. My only complaint is the buckle for the harness only fits in the outboard seat belt slots and when we take our kids in the back seat we can not use it. The middle row on both of our Fords uses a different clip profile. I would give this product a 5 star otherwise.
