I like to take photos of dogs using a wide angle lens on a Canon 60d, with a fast shutter speed, AI servo mode and continuous shooting mode on. I'm usually holding the camera low to the ground and therefore I'm shooting from the hip so to speak and relying totally on the AF system. I always have used the center AF point because I like to control what I focus on, but I often times end up with photos where the dog is out of focus because it was off center and the center AF point wasn't covering it.
Should I continue using the center AF point or should I use all of the AF points with the assumption that the dog, which will be the closest to the camera, will get focused on? Or should I be doing something else? I can't really do pre-focusing or manually select the focus point I want because usually the shooting environment is very chaotic (i.e., lots of dogs walking and running around).
