Several reasons: Torque. Back legs on quadrupedal animals like dogs are very strong, as they're used to push off during a sprint. The back leg can scratch harder than front legs.
The Short Answer

Most dogs can barely get their front paws over their snout, making putting them places like behind their head out of the question. The back legs, on the other hand, can scratch far more areas, at least on the front half of the body. For the bottom half, dogs bite. Quadrapeds! Unlike humans, dogs aren't particularly dexterous with their front paws. They don't have fingers or thumbs like we do, so there tends to be less of a preference for using their front paws unless they really need them. You're thinking of this from the perspective of a 5 year old human who uses his or her hands for everything and generally only uses feet for walking. Dogs walk and are mostly equally dexterous with all four paws.
