Cooper is trying to fool me! Every night before I go to bed I let him out for the toilet. Then he runs in barking, gets his treat and goes to bed. For the past couple of nights now, Cooper has started going over to the grass, sitting down for a minute pretending to pee then running in for his treat. So I send him back out and then he does a pee. It does not sound funny, but it is hilarious to watch.
