There never to old to learn. I have a dog that i got a little over a year he would not run the treadmill ether. I put him on there and he would just grasp it. So the next day i put him on he does the same thing again. The next couple of day i put him on after i put another dog on there that runs it a let him see and praise the dog that was running. He still did the same thing. So i repeated this for a couple weeks. One day he start moving it i seen this, so while it look fun to him but he was still kind of cautious, before it got to be not fun to him i took him off and praise him. After awhile of this he started to run the mill One time he was running wide open and all of a sudden stop, it was like he wanted to see what would happen if he would stop. He seen that he wouldnt fall off or get injury he been running the mill great ever since. Now we working on the springpole. It might not be easy, but it can be done.
