Jerry was one of Brian's nine siblings from his litter in Austin, Texas to Biscuit and Coco.
In the DVD version of "Hannah Banana". Stewie forces Brian to help him get into the Hannah Montana concert by tracking down all of Brian's litter and subjecting them to a possible horrifying death, including death by chocolate, a guillotine, iron maiden and drowning. Using Jerry as an example, Stewie blows his head off with an explosive collar. Brian gives into Stewie's demands when he sees what is in store for the rest of the dogs.
