Silly puppy

I went to the store earlier today and when I got out I put Shermans jacket on and started walking thought the parking lot. Halfway through the parking lot Sherman stopped dead in his tracks. I looked back at him and told him "lets go." He started walking again but was walking sideways and grapevineing (is that a word) behind me. It was pretty funny looking. I couldn't figure out what was wrong with him so I stopped for a minute and then tried "lets go" again, still walking sideways. So I checked his paws to see if something was hurting them. In the process of checking out his feet I realized that he had slipped a leg out of his jacket so the chest strap was under his left leg and went around his right. My silly pup is a little Houdini I still can't figure out how he slipped a leg out. I was laughing pretty hard, what a goofy pup!
