We went to Las Vegas to visit my sister over the 4th. While we were there DH and Nigel took one of her dogs for a walk. He was marking territory while they went and Nigel asked what he was doing. DH told him that he was just letting the other dogs know that he had been there. On the way home Nigel suddenly had to go to the bathroom. He does not generally give us much notice and as we were in the middle of nowhere we just pulled over. This was the first time he has peed outdoors. He looked up at DH and said, "Dad, I am just letting everyone know I have been here...Just like Buttons."
