The West Tennessee man is offering a 10-grand reward for Dakota, a black Labrador retriever.
The dog was stolen from the back of Volner's pickup truck in Paducah, Kentucky.
Volner tells The Paducah Sun he and his late wife didn't have any kids.
So, he says Dakota was part of their family.
Volner says he's gotten responses to his reward offer, but no solid tips.
He adds if Dakota is returned he won't ask any questions.
