This makes me question what is should mean to "win" in a genetic sense. The dog may be high in number, but its genetic selection has been artificial, controlled by humans selecting for favourable traits. Similarly, could we consider the cow to be successful, having been bred to produce enough milk that it can't stand, yet with a population much higher than before humans?
