You really shouldn't treat them both equally - first dog first is always a good rule of thumb.
My daughter bought a house and moved in this week and her basenji is having a difficult time of it as well - too much too different - but she's getting it. Kristen had put vinyl down in a small office in the lower level and made it a 'dog room' Thumper has a big pen with warm cozy things, lots of toys and her varikennel should she need to be alone in her cave. IN the previous house she had the run of the house but until Kris is sure that she knows the rules on where to stand if you want to potty, etc - she'll be confined there when no one is home.
She is not amused with Pergo floor - too slippery!
