Basicallly I'm after what east coast discribbed as a working terrier.. the type of jack Russell my granda had, a real character with more shape and better traits than the typical "pet". it won't be my first dog I've had working springers lurchers (whippet cross with a colie grey) and still have two other dogs ones 10 the others the far side of 13 but both still nut cases.. But I haven't owned a terrier And know there a different animal so want to do my research before I jump in
