Thank you for the constructive advice. I will try all these things. She did attend a puppy training class for six weeks in the summer. She did very well and learned a lot of general obedience. I have an in home trainer coming next week to help with this specific problem. She is much better then when she was a small pup so I'm sure she will only get better. I just worry about the poor cat. He is so gentle that the silly bugger won't give her a good whack or bite. I'm sure that would put her in her place. Thanks again everyone
