An animal control officer took custody of the dog and determined it was microchipped, and its owner lived in Maricopa County.
"Numerous calls and messages by CCSO Animal Control were left for the owner with no response," the sheriff's office wrote on Facebook.

On Sept. 6, the dog's owner, 62-year-old Karen Black, was found at her home in central Phoenix. Authorities say Black initially said she was never in Cochise County but later admitted to leaving the dog on the side of the road.
Black is accused of cruelty to animals and is due back in a Cochise County court later this month.
CCSO says the dog is being held at a shelter until Black's case is resolved.
