First thing to do is to read up on it, there are many handy greyhound books (use the Australian version as the overseas would be using different methods to us Ozzies) visit a lot of farms, have a chat to the rearers/trainers in your local area.

That way, you would get a lot more help than asking on an internet forum as it's much more practical seeing and hearing it in person from these rearers/trainers, and also handling a greyhound so you know what their personality are like. They're certainly not like pet dogs! lol they don't sit, stay, beg or fetch sticks/newspapers ;-)

Plus it's so easy to teach a pup bad habits, that they will never make it to the racetrack, if spoilt too much, or not handled enough, or not wormed properly, or not galloped enough or not galloped properly on the right surface (pups being reared in dusty yards with hard ground, are less likely to make it to the track without chronic injuries) etc etc

So the best place to start off with is to SPEAK with rearers/trainers in person. And pick up a rule book from your local greyhound racing authority, some forms as well for licensing costs of being an owner, handler, costs of naming a pup, etc etc

I reckon all young people should start with getting an older greyhound, that is ready to race/or already racing, have it with a good trainer, as this is the best way to learn quickly and gain all the information you want about the sport, because you will be at the track watching your dog racing and talking to other owners/trainers and making heaps of new friends!

Pups are sort of like an investment, you would have to spend a lot of money and you won't see any results for a fair while and there's always the risk after you've outlaid the purchase price, paid for rearing up to 12-14 months, paid around $300-350 for a month's breaking in costs, paid for the vaccination, naming and then for pre training (which can cost about $70 to $100 a week for as long as the pre trainer thinks necessary) and then you find out the pup isn't good enough to win a maiden.

Unless you're a pretty well off guy in permanent employment, now you can see just how expensive it is to get started with a young pup ;-) (unless of course you go the syndication route, which is pretty cheap and a whole more fun!)

Good luck in your pursuit! Hope you will keep us updated with how you are going.
