The smallest police dog is Midge, a chihuahua / rat terrier cross who measures 28 cm (11 in) tall, 58 cm (23 in) long, and who works as an official Law Enforcement Work Dog (or 'Police K9') with her owner, Sheriff Dan McClelland (USA), at Geauga County Sheriff’s Office, Chardon, Ohio, USA.Midge passed her Ohio Certification as a Narcotics Dog on 7 November 2006, meaning she is alert to the presence of marijuana, she can be used for arrests, search-warrants and drug-seizures, and her actions are recognized by courts and judges.Midge accompanies Sheriff McClelland on all his daily meetings and call-responses, she partipates in search demonstations and anti-drug messages to the Public, she is small enough to search school-lockers (completing her first at only six months old!), and does regular drug-checks of inmates' property at the county prisons.
