Hey, folks - do not mistake ignorance for stupidity. If you had never seen a Gentle Leader, would you know what it was? No. It is up to us, as pet lovers, to explain to each and every person who comments - "No, it's not a muzzle, it's a special leash called a Gentle Leader so she cannot pull me when I walk her. No, it doesn;t hurt her, it is just to correct her pulling."
Yes, this may get tiresome the 50th time you have to say it, but until we educate people, they will remain ignorant.
