Awww! Chewbacca is just precious. (PLAYDATE!!!!!) : ) Did she get him at the shelter on Bradshaw? That place is just depressing. I'm so glad she got him out of there.
Definitely remind her that Chewy has been through a lot in the past couple of weeks, and he's probably a bit scared that he's being abandoned again. I would recommend dedicating plenty of time to getting him crate trained (feeding him in there, giving him chewies and stuffed Kongs in there, spending short periods in it). Because she doesn't know if he's destructive or has seperation anxiety, and because it's not very safe outside for 8 hours alone, a crate is probably the safest and most comforting place he can be. Also, if she doesn't already realize, remind her that Poodles are ACTIVE dogs, and he should be getting a nice long walk/run and play time before and after she leaves for the day.
