I love the techniques. Bribery works well. Chicken in your hand works even better.
What I do for action shots is line up my shot in the area I want them to be in ...then sit and just snap away - I take LOTS of pics too - you're bound to get a good one if you take 50 at one time.
then I delete all the empty shots and blurry butt shots. The cute butt shots I keep.
