I had my jaw fractured by a dog wearing a Baskerville type muzzle(it was a Springer) so I know first hand how much damage can be done even if the dog can't actually bite.I think you are this dog's last chance of a loving home and I wish you well with her but PLEASE don't ever let her off her lead even when you think there are no dogs around,its just not worth it.

> I've been everywhere today and not managed to find a Baskerville to fit her.  I was surprised, considering how many Staffies there are in the UK.

This place has extra wide muzzles They are light weight, soft plastic instead of the metal cage sort, I've never used this sort, I've no idea how good they are? There are loads of on-line shops that have big ranges of muzzles.

>Well, it will take a lot for me to give up on little Stella.

Good for you I'm sure you'll have many happy years with Stella, you've just got to keep her out of trouble.
