been said before but it depends how your pup comes, could be a merle greyhound or could be more collie brained, that's where the "at least I know what I'm getting" line falls down with dogs imo. My only collie cross was a 1/4 beardie in breeding and looks(and speed?) but id say more in temp, the 1/4 gave him coat, nose, attitude to work blah blah
