This is Derek. He was dumped in a California shelter, horribly afflicted with mange. The Doberman Assistance Network pulled him, and named him Derek, and now they're working on getting his skin condition under control. He's apparently also hypothyroid, which has an effect on hair and skin. He can't go to a rescue until his skin condition is taken care of, so he's being boarded for now, at DAN's expense.
You can make a donation towards Derek's care on the Doberman Assistance Network sponsorship page.
