Glacier, the one with his back to the camera is the grandson of Two Socks from Dances with Wolves. He was bred for a certain look for the movies as was his grandfather - but he just couldn't cut it in Hollywood, lol. Kept missing his marks, stuff like that. So now he lives at the Wolf Sanctuary with his buddy Chipper. Chippy was bottlefed by humans, so he's super friendly, constantly posing for the camera. Tfl.
