I have always wondered about a pure greyhound myself.You wont get a faster dog and as for stamina,it's not everyone that wants to catch dozens of rabbits or 5 hares at a time.I think if properly entered to hunting, as already said, they would make a good hunting dog.I hope you go for it.I have 2 lurchers at present but would seriously consider a pure greyhound when I next need a new dog.Keep in touch with the site as I would very much like to know how you get on and I think there are others on this site who would also be very interested,All the Best,Woodbine.
