Sorry Blake but I don't really agree with what you've said either, like small Staffs? no brains? not sure where you got that info mate.
KinderBeano, For Ferrets and bush work, I'm led to believe that Beddy Whippets are excellent, but as Rough coated said, if you plan on doing lots of bushing with the dog and you only want a terrier then a good thick wirey coated out of dogs who do a lot of this type of work would be a good idea.
