That's just sad. I would take her to the vet to have her teeth looked into and see if there is anything else physical that she need.

You need to treat her like a puppy, because she has apparently never had any training. This means she has also never had any attention or affection, so just give her lots and be patient with her. Since you are the first human to ever be kind to her, don't be surprised if she gets really strongly attached to you! These deprived dogs often turn out to be extremely loyal.
