That's what his owner called him as he tried to get him to return to his master. Mr Mud was in a mad dash towards me as I was brushing out the van carpet. I saw them on the beach so I knew exactly what was happening. I did not look up or react in any way. Suddenly Mr. Mud stopped at a safe distance and stopped barking. I looked up and took three images. This one shows best that he was a little uneasy about coming closer. In fact he was ready to retreat back to his owner. Looks like a Chow mix. Intense little guy.
