Ketu Willow the Tibetan Terrier. Hello, my name is Ketu Willow. I am a lovable, frisky Tibetan Terrier. I am hypoallergenic--I have hair instead of fur. My hair can grow very very long; it can touch the floor. My folks think I'd be good at agility because I'm very fast. I am also quite smart; ask my Mom. I trick her all of the time--she'll say sit and I'll lay down just to keep her on her toes.
