All excellent advice, not much I can add. I have a 9 week old Samoyed here and I'm pretty much kangaroo momming him. Right now he's even sleeping with me. Fortunately I have my daughter and her father helping out so I get some breaks, and my daughter does most of it when she's home 2 days a week. Samoyed are extremely people needy, but honestly I am the one who can't bear him being on his own too much this early. Even with doctor appointments, he has a crate in the living room so Larry can take him out to play/potty and snuggle (since I'm usually gone 5 to 6 hrs some days).
Easy adjustment.. put in crate, happy voice "i'll be back" and leave. Go out the door and leave alone at least 15 mins. Keep extending it over several days until you are up to a couple of hours. By that point, they do get you will come back. Just no drama, no soothing poor baby stuff... nonchalant. Happy leaving, happy return. Make sure safe toys, chews in crate.
If you can arrange it so her work and your's don't quite overlap so he's no alone more than 4 hrs, that would be idea. If not... swap out coming home for lunch break?
Good luck.. and please post pictures :) Also, where did you get him? A lot of the basenjis here are related. (My basenji now is a rescue so not related.) It's nice to see the connections though!
