I got my carpet mill, Mazie got on it and ran like crazy it was so awesome to watch. I need to monitor her, I can't believe how she understood it. My other too are slower and need to be baited but I suspect they will eventually catch on.
Its a great mill for the price. Its very solid and runs really smooth. My girls run it pretty hard, My male flat out refuses , he wont move for food either. Have any experience with a stubborn dog? I would recommend this brand as their customer service was fast and friendly.
