Update on Bella:
So far so good. We are now getting about 7 hours of whine-free sleep per night. She's sleeping in a doggie bed next to ours and doing well. I still have to crate her when in the shower. After raising 2 other B's, I'm scared to death to leave a puppy unsupervised; even for just 5 minutes.
Only one potty accident in 4 days, and that one is my fault. She was standing in front of me whining, and I thought it was because my wife had gone to bed and she wanted to play with her. Not so - she needed to go outside to pee.
In the last 24 hours she has figured out how to: do a solo Basenji 500, jump up on the couch, nab food out of the pantry when we open the door to get something, chew everything in sight, and walk fairly well on a leash. Tomorrow she goes to the vet for her 2nd round of puppy shots. Tuesday will be her first all-day home alone. She seems to have bonded really will with both my wife and myself.
One of my good friends and his wife have adopted her last remaining sister from the BYB, so she should have a good home as well. They've never had a dog before (much less a but do have 7 cats. So far, everyone is getting along fine and I've hooked them up with all kinds of info on B's.
