I have recently taken in an abused male Great Dane from a shelter he was being held in, until his time ran out. I saw him, and fell in love with him right away. But I've been having trouble with him wanting to bite people that get close to him or me, even with family. He's became protective of me since I spent the first few weeks laying with him and getting him back to health. Is there anything I could do to make him stop wanting to try and bite people when they get to close? I've tried telling him no in a soft voice and he freaks out and runs from me from time to time.
Any help would be appreciated, I love him to death and I just want the best for him.
