Do they look excited? We recently bought this to take the "kids" along on our bike rides. The girls were all for it and behaved perfectly. Henry was, well...Henry. He has to stand up and bark the entire time. It's like he's the town crier, and he thinks he needs to announce to everyone that we're coming. We rode about nine miles round trip to the bark park and back. I thought they'd be pooped from running at the park. They were, but Henry's still found the energy to announce our return. Mr. B is going to get a good workout pulling these three.
