Running with a Dog

I've been taking Cliff on "jogs" because he has too much energy for walks most of the time. He hasn't quite got the pacing thing down and it was one of my goals this summer to try to train him to run beside me. This is where we're at currently if it's any indication of the progress:

A little bit of work to do.

It's been busy around here though so running fast isn't necessarily a bad thing!

Have you ever trained a dog to jog? Tips and tricks appreciated :)
