Yup, that is normal. I have 3 basenjis - they do the b500 many times daily (sometimes indoors, sometimes outdoors). Personally I love it - even in the house. Of course I need to replace our wood floors because of it (need harder wood).
I have a 13 mo. old pup, and she is a pistol. I use training and interactive treats (kongs, busy buddies, squirrel dudes) to slow her down. Oh, and the 2 adult basenjis also help with her - but she is a bit of a jester so you never quite know what she'll do next. Her latest thing is opening closed doors (putting her paws on each side of a door knob and turning it to gain entry to a room).
I'm with the others - it sounds like she needs more exercise. If outside exercise is tough because of the weather, do you have a treadmill? One thing that I do if the b kids are over the top, I will do some training with them. A short 5 or 10 minute session usually stops unruly behavior in my house.
I agree with Pat in that it is too bad she is being crated for normal behaviour. I pretty much only crate for meals and when I'm away from the house - never for punishment as I want them to never fear their crate.
