Really good, sturdy harnesses which are easy to use once fitted. Think the dogs have a much better chance if they are in an accident than in their previous, less chunky, untested ones. Be mindful of sizing, both my dogs measured medium according to on-line sizing but when they arrived there was a weight limit and my big boy needed the larger size. Dfordog was amazing about replacing the item, working over the weekend and getting the new size sent out before the previous one had made it back to them. 10 stars to dfordog.
