Wow You are lucky to have him on it willingly. Good way to burn off some energy on a rainy/snowy day.I have a treadmill that I walk on every night and a couple of days ago my GSD decided he'd walk on it with me. :wild:
He walked right next to me and then he kept getting closer and closer to me until he had me stumbling on the sides! I got off and he kept walking on it, it was one of the funniest things I have ever seen!
