'Stuff on Scout's Head' Dog Dead at 12

Scout -- the pitbull terrier who became a viral sensation for balancing just about anything on his head -- has gone where all dogs eventually go.

Scout's owner, Jen Gillen, tells TMZ the 12-year-old dog became extremely sick. He suffered from seizures and had a tumor removed. He also battled diabetes.

Jen tried keeping Scout alive, but it got to a point where he couldn't eat or drink, so he was euthanized last week.

RIP Scout, and say hi to God.
