If your just gonna use any Greyhound for breeding then you might just as well say then that ANY Saluki,Collie,Bull,Whippet or whatever will also do? Bollox ,that's where i've being going wrong,should of went to the dog refuge and picked up a stray ,if your happy to have moderate dogs (like me) then YES any Greyhound will do but champions and their kin are what you want pups from that's if you want the very best Like catcher1 said,Greyhounds have more than enough fire in their belly,unlike most lurchers they will KILL anything so saying they ain't game is ludicrous imo.All the best PP.
