lizbud,
the harness is not scratchy and it fits fine. Right now, she is wearing Ricky's old one because she chewed hers in two. She just doesn't like anything going over her head. Once it is on, she is happy and forgets about it. She has been this way since day one.
I think we will have to use the treat system for a while. The main thing is to stay calm and not make it any more stressful for her.
