The girl's mother said the 7-month-old French Brittany was found along the side of the road in the area where he went missing.
"We are struggling with the fact he was out there for a week and no one saw him, especially since we canvassed the area." Michele Kelly said.
The family plans on an autopsy to confirm when the dog died and to see if his injuries are conducive to being hit by a car.
The family has set up a GoFundMe page to help cover the costs to train a diabetes alert dog.
