Photographing fast-moving dogs is hard enough and one cannot really shoot for composition. As a result it sometimes becomes necessary to trim images to obtain better framing.
Image editing that involves trimming and shadow/highlight adjustments (or HDR if that at all is possible) comes in very handy in canine photography.
