One of my parents' dogs, Tank, died this past weekend. He had bone cancer in one of his legs so each day was sort of hit and miss, but then yesterday he went to stand up from a laying down position and the bone snapped, so they had to take him to the Vet.
Tank was always my favorite. you can't tell from this picture but he was HUGE. When he was up on his hind legs he was taller than me (not that that's saying much). He was also very playful and fun, and he'll be greatly missed.
