Boy, that's a tough one. I think I would want to be 110% committed so it isn't necessary to re-homed a second time. I'm not sure if her presence would have an effect on Peanut's potty training. I took on a second girl for a time and she wasn't potty trained. Sophie was and she didn't slide at all on her training. I guess I'm not much help
. Good Luck in your decision.
