have you thought about contacting Cesar Milan to see if he could help place the dog after working with him?
From their website:
We appreciate your concern and your passion in aiding dogs in very unfortunate situations. Cesar and his entire team wish that there was something they could do personally for every one of these dogs, but as you can imagine, we receive hundreds upon hundreds of these requests each week, and sadly, it just isn’t possible. Please know that we are working diligently through the non-profit organization, The Millan Foundation (http://www.millanfoundation.org), to support the work of shelters and rescues across the country that are doing all they can to fight pet overpopulation. It is our hope that one day we will be able to help each and every dog that finds itself in such horrible circumstances.
