Now, before anyone starts talking about there being no bad dogs, only bad owners, let me explain my friend's situation.

She found what looks like an Aussie Terrier tied to a tree outside her work five years ago. Since then, he has bitten her to the point of stitches, bitten her daughter, and ruined most of her carpet and furniture with his refusal to go outside to defecate. Her kids are afraid to touch him due to the biting, he hides under the bed and tries to bite when it's time to go outside, and then runs to the living room to pee/poo as soon as her back is turned. She can't leave him outside because he barks incessantly, and he shreds anything he can pull out of the garbage can, off the sofa, etc. As he's gotten older, the food aggression and destructive habits have escalated rather than eased.

Now to my point:

She can no longer subject herself or her kids to this urine-soaked environment or the danger of his temper. She cannot in good conscience adopt him out or give him to animal control/humane society without disclosing his biting. She is trying to find a rescue organization that would be willing to try to rehabilitate him (no idea why he acts this way), in order to avoid euthanasia. Does anyone know of a group in North Georgia that might help?
