Duke is wearing me out today! We did our long walk (3 miles) even though it's freezing out in Chicago and sidewalks were slick. We met a new golden (Rowdy, 1 year old, +107lbs golden) on our walk and played for a bit. Then it was time to come home because the weather was starting to get worse. Duke has started this new thing on our walks. If he thinks we're turning around too soon he starts running in circles at the end of his leash and trying to play tug of war with me. Once I get that under control and bring him home, he's managed to train me me to take him immediately to the back yard to play with his jolly ball (again he likes to play tug of war - which I don't mind doing - some). But he can go and go and go... Since it's so nasty out today, I've thrown the tennis ball for him to catch and bring back to me for 45 minutes this evening inside the house. That didn't manage to wear him out. He still wanted outside to play with his jolly ball; which he preceded to bring to the back door and scratch the door. As soon as I would open the door to let him in he would take off running. He wanted me to come outside and play! What do other folks do to get some of the energy out of their goldens?
