How about pheasant hunting in PA? Essentially no pheasants survive the winter. Phaesants are raised and released every year. A few are killed by hunters. The remainder starve to death over the winter.

Second, I don't consider torture to be an essential part of dog fighting. If we are to contrast dog fighting with hunting we should do it on an apples apples basis. Good dog fighters against good hunters. Or, perhaps, jerk dog fighters against jerk deer hunters (not found on this forum, of course!).
