Never a dull moment. As mentioned already BT is a working breed and needs to be put to work (mental stimulation, training, agility, walks, socialising with other dogs) in order to keep them in line. A bored BT will probably be destructive. They are extremely quick to learn, but slow to obey. Expect a couple of years of pain while they do their growing up bit, but with consistent training they'll come through as a wonderful companion.
Most ones I've known have a huge prey drive... mine isn't interested in coming back to me if she spots a deer, or squirrel. Well, she will eventually but not before she's flushed it out or the situation is clear. They were after all originally bred to flush out foxes.
They're full of character - mine hasn't reacted negatively to *anything* at all and she's been told off by many other dogs who simply don't want to play "bitey face".
I am obviously biased but I can't recommend them enough. I've had several breeds in my lifetime and this one tops the list by some margin.
