I agree with that mate, I used to keep digging blacks thought I would have a big change and go down the Russel route.. all black dogs got strong dogs in them way back some not so way back, I have seen quiet a few bull russels even first xs that can be dug too, just thought working Wheaton would be better than a bull to use, as only access to proper bulls I got is big ones, plus don't want to go to another strain of working terrier that would be too easy ?
