BigDog at the rescue center.
He was a shy, gentle giant (almost 40" at the shoulder and 150~ish lbs) that he suffered very few to touch. I was one of those lucky ones that he would allow to touch, walk, and groom him.
He could put out an amazing quantity of fur when he shed, too, with a double long coat.
They said he was a wolf, but my suspicious is that he was a mix between Shiloh Shepherd and Wolf.
