A guitar donation from Carrie Underwood could help save an Oklahoma deputy's canine partner.

The Muskogee Phoenix reports Underwood donated an autographed guitar to help pay the medical bills of a McIntosh County Sheriff's Department K-9 officer. Underwood is a native of the Oklahoma city of Checotah.

Deputy Kevin Branscum has partnered with the German shepherd named Gino since 2012. He has spent around $4,000 since December for medical care after the privately owned service animal was infected with heartworms. Gino has medical treatments scheduled through May.

Officials plan to auction the guitar but haven't set a venue or date. Branscum says he was surprised by Underwood's donation and is incredibly grateful.
