Whippet racing is the same as greyhound racing, only with whippets. this is not racing for money, like some people do with greyhounds, but it is mostly for fun. the dogs are put in the trap, which is a metal box with bars at the front. when they are let out, they chase the luar, the dog who is first wins the race. some people do whippet racing for a hobby.
It's not an age question. It's an ability question. If your wins are not FAR outpacing your losses it's time to make a change. Good racers find a way to win. Do you have a good coach/sponsor??? Get one or get out.
