Well, when we hit the first restaurant, Nino was far from tired. In fact, if I slowed down, he would push a little harder and pull the bike. When we hit a hill and I struggled to get up it, my dog decided to help me out. He LOVED it! I’ve never seen him so happy to go somewhere. It was awesome to watch. I imagine he liked to pull the bike because he’s a working breed, so it fulfilled him somehow and let him use his muscle.
