The Chihuahua Race is a minigame in God Hand that you unlock after beating stage 2.

Depending on how low the number of the odds are,the more likely it is for the chihuahua to win.

The money you win is Money Bet x Number of Odds,meaning if you pick a chihuahua which is unlikely to win and he wins,you will get more money than a chihuahua that is very likely to win.
