sorry Rachel I just remembered about the clicker thing.
You know you can get clickers with a volume control for dogs that aren't sure of the noise?

I might have a look for one of those then.

There are 3 levels of sound adjustment this is the one we have.

I hope you get something sorted for her Rachel, it's horrible to hear them yelp like that isn't it? Would Fudge sit quietly for you while you place a treat on her nose? That way it might become a fun game for her and you're also putting things on and around her nose.
