Dee, i've seen quite a few Gouldy bred russells 'work', back in the day when Flint was alive, a fair few were pups off him, never seen one that i'd feed, never mind own. Maybe now there are decent lines off that stuff but this far down the line, if they are any good, i'd be wondering what, of the old stuff, would come back out in any future litters to bite ya in the ass!
