I imagined a big dog of some sort hehe, if she was a big dog then no doubt about it i would'nt of taken the chance because of the amount of damage she could well of inflicted, but after reading what breed she is and what she is doing i now say give her some time, i doubt she would do much damage bless her lil cotton, and as long as your 100% your other dogs will put up with her mood swings while she is trying to settle in i now think you should give her some time and im very sure in time she will get used to your routine and also realize the other dogs are her freinds .

love to see pictures of her if you have any done
