If u used a digital Camera, I can kinda tell u why thay all turned out blurry.

I bet u had it set to Auto, right? Well auto SUCKS for moving objects (I never ever use auto)

I forget what its called, cause the camera isn't near me, but its an action setting, mine has a running man as the button heheh. Its great, I only use that setting, unless I'm making videos.

SO try using the action setting, test it out with ur pups running around & see how they turn out. I know they'll look MUCH better
