I think they are my favourite breed. Intelegence, trainability, loyalty. They can be wonderfully sensitive to their owner once there's that bond and respect. Or they can be manic idiots if left to rule the roost or get bored. Good to find ways to keep their brains working. To be fair, probably true of most dogs, but I don't meet many terriers that have been even half trained and many collie, spaniel, lab types seem wired to a squeaky toy or treats rather than tightly bonded to their owners iykwim?
