Sheriff's Sgt. Sean Hartman, who runs the sheriff's office Facebook account, had stopped by to check on Smith and ended up capturing photos and video of the ensuing chase.
The Facebook photos show Smith running after the cow before safely returning her to the barn.
"This cow was cited for failure to stop at a stop sign and interference with official acts," Hartman wrote in a comment on one of the photos.
Scarlet's owner, Emily Manweiler, said the bovine was unharmed.
