Does anybody know if there is a bigger version of the gentle leader? I believe gentle leader is really the name of the trademark, rather than a general product description, so anything that works similarly would be helpful, as well. The current one has worked pretty well for us, but is getting a little tight. Ironically, the Mastiff in the picture looks exactly like Bane, but it‘s just getting too small. Second question: does anybody use a second leash hooked to the collar in addition? We have never needed it, but it seems to be an additional safety measure.
