Remember, it's not the dog in the fight, but the fight in the dog that prevails
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.
But only if the dogs are more or less evenly matched
Throughout nature the little guy is often given a secret, sometimes deadly, advantage over the larger animal. Take the scorpion, black widow, or porcupine. Porcupines don't get eaten.
Of course, I can't disclose MY secret, sometimes deadly advantage. : )
