You can't win races!
there are several issues
1) Your dog never wins, I went threw the game building up my dog and never got past 3rd place
2) the only real way to build up money is betting on the other dogs. Here's a hint bet the max on Ball and Chain. he wins 90% of the time
3) items don't help and are too expensive. Here's a warning do not I repeat do not buy the jet pack it's $55,000 and it will not help your dog win at all and every time you use it you get a $25,000 fine!
4) I don't understand how the bills work. one race i'll have $0 in bills next time it will be 10,000, next time its $2000, then up to 15,000 it's quite confusing as it doesn't seem I'm doing anything to cause bills to fluctuate so much
