This lead is meant for the breeds who use a choke chain, or collar or even a harness with a D ring. It's a very strong lead, ALL breeds can use this lead. It attaches to the ring of the collar easily. The snaphook is sewn in securely, for when you want to use the same lead with multiple dogs and want to change over quickly. It comes with a lightweight silver snaphook, which is fine for all breeds. If you have a dog that pulls very hard, I do have heavy weight silver snaphooks that cost $2 more. I also offer gold (brass) lightweight snaphooks for $2 more, choose that option and specify which one, gold or large.
