Hey Ash,

I have to use a muzzle on Smudge only for a different reason. Smudge needs one when he is kenneled otherwise he stress barks and it's not good for either of us. If it wasn't for the fact that Chewy attacked Teddy over a piece of foil I would just say it's part of her nature, but that sounds like more of a possesive thing then nature thing.

I'm not going to tell you yes or no about the muzzle though, it's something that you have to decide about on your own. I know it was a hard decision for me to make with Smudge and I still don't always feel great about it, but I had a choice of either muzzling him when he was in a kennel and letting him bark when he's outside (he doesn't bark all that often outside) or get him devoiced something I really did not and do not want to do. But all I'll say is do what you think is best for Chewy.
