Need some dog advice please?

Sounds like room and money aren't issues, she's healed and doing well, and you really want her. What's holding you back? You are the only one who can say if it's 'too much' for you, not anyone on Yahoo Answers;). I say take her in, if it's a big problem for you (or the other dogs), just see about getting her a new home. I'll bet it will work out just fine, though. Go for it!
