Well we tried them both on the tredmill, Perry went crazy didn't want any part of it.
We put it on as slow as it would go, but even holding him he would jump off, on the other hand Miss Daisy didn't mind it as long as we held her up a little she would walk on it. So she may do it, I don't think it's an option for Perry. Here is a photo of Daisy walking on the tredmill with Don holding her a little. We got a good laugh out of this. Jackie
