eh she'll get stick for this, but if she has the money/resources to make sure they're well cared for, then i don't see the problem. it might even encourage her fans to adopt rather than buy.
I think it's dumb that she'd get anything negative out of this. She's rescuing dogs in need of a good home, she can more than afford this, and like you said, it may encourage her fans to adopt. A+++ on her part.
