This is both a practical guide for people using terriers as working dogs, and an interesting account of their history. There's a good account of how the different terrier breeds are used in pest control, and there is a lot of helpful advice on caring for terriers.
It's clearly written enough for novices to follow, and there is enough information to interest experienced owners and handlers of working terriers. It's well worth reading, just to get an idea of what your terrier was bred to do, and to understand why he behaves the way he does.
