I want to buy a horse for racing!!!

Well, I sure hope you have lots and lots of money. I don't know how things are in your country, but in the United states, a good racehorse is very expensive not to mention the training that goes into it. And, even with a good bloodline and training, it doesn't mean that your horse is going to win. I used to know someone who had a horse racing farm and most of the horses they owned made very little and ended up being auctioned off for dog food in the end. If you have a lot of money and your own ranch, then you'd want to buy several with good breeding to get started. It's that one or two that win that will make you the money. If you are just planning on breeding or training, that might be a better option, but you still need to breed and train winners to get a reputation as being a good place to buy from.
