Hey welcome to the forum!
As you are new to the sport i would suggest buying into a syndicate to start off, you would be best to buy a share in a pup which will allow you to lear the in's and out's of the industry. It also reduces your initial outlay.
Some syndication providers are
Team Bundy Greyhound Syndicates
www.greyhoundsyndications.com
Wahoo Racing Syndicates greyhounds breeding pups for sale
