The office received a report that K-9 Axel was left alone for more than 20 minutes by his handler in May.
The two were allegedly playing fetch, when the deputy got a call about railroad gates blocking a road.
The sheriff's office says the deputy responded to that call, leaving Axel behind, and that a member of the community later found Axel eating grass in the field.
After an investigation, Axel was removed from the deputy.
Deputy Chief Chris Covelli said in a statement, "Axel is healthy, capable of continuing to work, and is expected to have several years of productive service life remaining. Several law enforcement agencies have expressed interest in acquiring Axel."
Axel is being cared for at a K-9 training facility while his future placement is finalized.
