Swaggy Wolfdog has lost something very valuable and Grant Prestonis willing to offer a "big reward" to get it back.

A cash reward was advertised on social media Tuesday to anyone who could ensure the safe return of the celebrity canine's missing $100,000 chain.

"Can't believe this happened to Swaggy, he lost his brand new $100k chain at an event this past Saturday," Swaggy Wolfdog's people wrote in the caption.

Anyone who found the customized chain, which has Swaggy's name and a Swaggy pendant, was encouraged to reach out.
