Ok, I have been trying to come up with creative ways to drain Dycen's energy. I have noticed that he has become bored with the agility jumps. Has figured out he can retrieve the rope a lot faster by going around and I am running out of places to hide things. I have taken to notice he LOVES to pull my son and daughter on their trikes, however, I only have a regular walking harness and tie the leash around the handle bars. I would love to get an actual carting set up for him but don't know of anyplace that makes or sales them for dogs under 50lbs. Any suggestions????
