I had a cocker spaniel that had been abused. I got him when he was 9 mos old and had him for the next ten years that he lived. He never got over his fear of men, feet, brooms, or anything coming at his face.

I think rehabilitation will vary greatly from dog to dog. The owners just need to remember that it's in the dog's own time that he will recover his life. And he needs all the support he can get. Poor baby.
