Mojo and the dog walker

There was a breeze blowing this afternoon that felt pretty good.  It may have been my imagination but it looked like he had a little "gitty-up" in his step.  I couldn't figure out if it was really something or not, he wasn't limping but his gate looked off.  I know his tummy always sways a lot from side to side when he walks but maybe it was more so than normal.  I couldn't tell if it was something in his back legs..., again I'm not even sure there was anything wrong at all. He also hadn't eaten his breakfast from this morning.  There were ants all it so I tossed it and gave him some more which he did eat.
