Teagan wears a muzzle, and to be honest only 1 person has said anything - and it was because she wanted to stroke her, and ask why she had a muzzle on!

At training class no one seems to care either!
Most people tend to avoid us - which I prefer

Trip used to wear a muzzle as she nipped my other dogs and occassionally ate anything she could get hold off!...

However - there are other ways to fill mouths. Toys are a great one. A big toy in the mouth does a couple of things...1 - makes the dog look a lot less threatening and 2 - stops her from being a gobby GSD!

My advice would be to work on the toy obbsession and get a greyhound racing muzzle (one with a filled in front).

We used to muzzle our old GSD (we lost her about 12 years ago) but if she got loose with a muzzle on she would just headbutt the dog.
