Lots of dogs, at least in cartoons and conversation, carry the name Fido, a testament to canine faithfulness.

But the police dog that ran away on Friday afternoon was named Bronco, possibly suggesting a streak of independence.

Bronco, who is employed by the Loudoun County Sheriff’s Office, “escaped from the groomers” in Leesburg, the sheriff’s office said in a statement.

As of Saturday evening, Bronco had not been found, said Kraig Troxell, a spokesman for the sheriff’s office.

On Dec. 7, Bronco and the master deputy sheriff with whom he works were among the recipients of a departmental meritorious action award. It may be given for either exemplary action or exceptional meritorious performance.

(As of Saturday night, Bronco remains missing.)

The office has asked for the public’s aid in locating the dog.

Bronco was described as an 80- to 85-pound dark sable German shepherd.

The dog was last seen in the area of King Street and Catoctin Circle and may have traveled south of this area, the sheriff’s office said.

Anyone spotting Bronco was asked to call the Loudoun County Sheriff’s Office at 703-777-1021.

It was not immediately clear how Bronco escaped.
