Billybones, I started back into greyhounds 3 years ago after a 40 year rest from greyhound racing. I pacificly came on these forums to gain knowlege by asking questions like you about racing greyhounds these days.
These people like Gippy and Nick especially have guided me in a way that I have had success with all my dogs so far. I have had 6 dogs and all have won (even had a a city win with one of them.) except one that unfortunately had a fall and had to be put to sleep.
I hope you listen to these people as they will steer you in the right direction always.

Good luck mate with your dog.
