A retired Philadelphia police canine has died, the department announced today.

Danny, a German shepherd who retired recently, served the city as a patrol and explosives detection dog since 2004. He and his handler Officer Jim Zimmerman participated in many Hero Thrill Shows, which raise funds for college expenses for the children of slain officers, and won several awards in USPCA police dog competitions.

"After retiring, K9 Danny enjoyed retirement at home with (Officer) Zimmerman and his family," the department said in a statement.

The police department uses 23 canines - 19 German shepherds and four Belgian malinois, said Officer Christine O'Brien, a police spokeswoman.
