why not? so if you owned a top class rabbit bitch and wanted to breed a pup of her and you new of 2 good stud dogs, 1 was a purpose bred rabbit dog and the other a failed hare coursing dog which was better on rabbits than the purpose bred rabbit dog would you not use the coursing dog?
if not why? if your looking to breed rabbit dogs wheres the problem. everyone always says do best to best breeding when you can.
