Most people I've come across say that if you don't have time to walk your dog you shouldn't have one. I agree with those people. However, I do remember last winter when there was about three feet of snow on the ground and I came across a feature of a woman walking her little dog. That poor dog looked like it was fighting for its life in the trenches. So, my thinking is that this little treadmill might not be a bad idea for small dogs during Utah's big winters.
