When Jason Diggs came downstairs from tucking in his baby, his dog was gone.
Not long after that, he came across a disturbing image of Tyson on Facebook.
The pit bull was photographed at the end of a short rope outside a dollar store - his sole company, a bag of dog food.
"I had no idea where to look," he tells The Dodo. "I had no idea even what side of town to look. Until I saw that post."
Diggs says his in-laws, who were never fans of Tyson, stole him. And abandoned him. Trouble is, now Tyson is missing.
"He's my dog," Diggs says. "I just want to make sure he's all right."
Diggs says he has canvassed the Bakersfield, California, neighborhood, even asking local homeless people if they have seen Tyson. Now the hunt for the beleaguered pit bull has gone nationwide.
Somehow, the dog managed to break free of the rope. And yet, he refused to move. Instead, the dog with loyalty as extraordinary as it is heartbreaking, remained, literally, at his post.
