well this is just my opinion, but its also a lot to do with what one describes as a "working terrier" !!
It seems that most of the people now a days ASSUME they have a working terrier, simply just because it has been born a russell a lakeland a fell or border, and it seems there is a good many men on here that think they have a working terrier because its been bred from such and such a name. they also class a terrier as "working" if it catches the odd rat or works rabbits in cover or runs the odd empty earth or artifical, or ragged a dispatched fox and growled its tonsils out.
