Look at his back paws

Not a good photograph by any means - just one of a few snaps I took on todays walk.
Converted to B&W in the hope of improving it a little - but the one thing I noted and the reason I uploaded this particular one is the position of his back paws as he jumps over the log. They are more or less ahead of his front shoulders. Quite normal I'm sure but I'd never really noticed before
