I would base that decision on a personal assessment - not on the opinions of forum members, and certainly not on the opinion of the person wanting to rehome the dog.
We got Molly from a private owner surrendering her. The previous owner swore she was fully-trained - not just house-broken, but trained in culinary arts and only a few credits short of her Master's degree in quantum physics. Also, really good at small-engine repair.
I realized the previous owner was exaggerating at least slightly when Molly jumped up and crapped on our new sofa.
My point, however, is that we adopted her for her personality and temperament and the quick bond she formed with Esther - not because of anything the prior owner said, and not because of anything anyone here said. (If I listened to everyone here, I'd have 43 dogs by now.)
