Hey Skamp..where in Ontario are you? If you are in and around the GTA then I suppose it will be hard not to have to follow the law. I am down in the Fort Erie area ina very small town so I am hoping and praying I can get away without. I just can't bear to do it. It makes our dogs so vulnerable. What is Scout, my Staff, supposed to do when the huge, scary GS comes charging at him and he can't defend himself? There are a fair amount of pitties in this area and I haven't seen any with muzzles on BUT I have been seeing them with Gentle Leaders. Interesting. Have used one on Scout when he was younger and was a puller. He just HATED it. Such a load of crap, this whole thing is. Let me know how it goes if you do get the muzzle.
