She was, however, the smartest critter I have ever run into. But, she was also insane (as borders will be on occassion). She was the most fun of any dog I had ever had; but, she was also the most work. I wouldn't recommend these dogs for anyone who can't devote a lot of time to them and who have a stronger will than the dogs. (I'm a wuss and tend to spoil my dogs, and this border knew it.)
