Tiki the dog helps Illinois man Chris Smith survive gunshot to the head

On Thanksgiving afternoon in 2021, emergency medical technician Dennis Hobson was summoned to a house in the tiny village of Farmersville, Illinois. It was the house where his friend Chris Smith lived with his dog Tiki.

What he encountered is the subject of "Fatal First Date," an all-new "48 Hours" reported by correspondent Erin Moriarty, airing Saturday, Nov. 2 at 1/9c on CBS and streaming on Paramount+.

A 911 call had been placed to the Montgomery County Sheriff's Office by someone checking on Smith, and Hobson walked into a bloody scene.
