Just a thought on this, if your AF is not in "AI-servo" mode, the one where it continuously focuses, and Jack is running toward you, he'll have shifted way past where the focus was set by the time you click.
So; half press and get the IS running, while letting the AF follow Jack as he approaches, then gently finish the pressing of the shutter to take the picture.
To clarify, if you have the focus in the mode where it gives a confirmation beep, that is not what you should be using for this kind of target tracking photography.
Cheers,
