Hedz31 this should be an intresting topic and imo the usual folk think they are dictaters or dog gods probably wont reply! Have i bred from dogs with faults,of course i have,but ive used my outcross dog that is known for the traits im looking to correct,be it brains,nose,steadiness whatever it may be. One of the best dogs ive dug to over 8 hard seasons graft was lifted on more than one occasion after failing to bottle up quarry,i dont mean after an hour it was more 4 hours of constant round and round,the dog showed and was lifted before flying back to ground,that was a failed dig in my opinion
