I use this leash with a larger sized black lab and a Great Pyrenees. One weighs 85lbs. and the other 130lbs. The lab is the heavy puller of the two, but if they get excited I'm in for an adventure!! So I've used this leash daily for years and you'd never know it, still looks brand new. Clips still function the same. Because of them two outweighing me, I do use the handle in a clip belt around my waist so I am the "boat anchor" and can still use my hands if needed. I don't need to untangle them every two seconds like I would with standard leashes (one wants to go full speed and the other wants to smell the daisies lol) My only request for a future upgrade is a waist attachment option for those of us that need extra support for extra large dogs. But regardless, absolutely best purchase I made for them!!!
