Honestly, if the dog is already really bad, 6 weeks isn't going to make too much more of a difference. AND if the dog is really as bad as you describe and you sister does not end up keeping it, I doubt she would wait for 6 weeks to let you have it. You know? I bet she will get really sick of it and call you and tell you to come get it!
I think if she keeps it for 6 whole weeks, then that means she really likes it and she is going to keep it. She is not going to keep a dog she doesn't like and isn't intending on keeping for 6 whole weeks! She'll hand it over before then. That's just MHO.
If you get the dog, you're not keeping it either, right? Or did I read it wrong? If you aren't keeping it either and you are giving it to someone else, is it really that big of a deal who it is acting when you get it? Maybe I misunderstood. Sorry if I did.
