Who's training who?

 Wally now knows the commands 'sit' & 'get down' and almost always does as he's told but this has brought a problem. He now thinks it's great fun to dive into the cables behind the TV and go crazy with them, shaking them furiously until i tell him to 'sit' or 'get down' which he does. He runs over to me and sits waiting for his treat. After eating his treat he goes straight back to shaking cables again. We must have spent 3 hours doing this yesterday. Great fun but I think he now has me trained good & proper.
