Mojo seems to be just fine. I think it may have been my imagination with something going on with his legs/hips. So sorry if I created any undue concern. We walked and ran again for 2 reasons: I seriously have something wrong with my left thigh and I was watching to make certain Mojo was okay too. He was, I wasn't. He was outside when I got there and the painters weren't there yet so I left him outside after our run.
