This was Levi's first "off leash" trail ride. He did really well. We passed several people skiing with/out dogs and Levi stuck to my back wheel. More interested in running with the bikes. It was - 7C and Levi was perfectly fine for the 1 hour run time. We did a lot of practice riding over the summer at a school with a fenced yard. He graduated to a harness and "tug and tow" hook up to my bike - much like a sled dog. That was fun - who needs an electric bike. And now we will slowly work with him off leash on some of the more remote trails in my area.
