Kinda. But only if the dogs are more or less evenly matched. A ten ounce hermit crab is not going to come out on top of a lobster. Two lobsters, one normal and one fat and twice its size, well, then "the fight in the.." comes into play, but I wouldn't bet against the in-shape lobster.
Put Propecia there against a guy in her percentile, and she wouldn't be able to even know where she was, let alone hit him.
