PLAINFIELD, Ill. (AP) — Dozens of police departments in the suburban Chicago area have joined Plainfield police to honor a 10-year-old police dog that died.

Authorities formed a half-mile-long procession Thursday from Plainfield's police department to its fire department in memory of Aron, the (Joliet) Herald-News reported (http://bit.ly/1pvpH4M ). They saluted Aron and his handler, Officer Brian Wagner, who received a service recognition award from the Will County Board during the memorial service.

Aron was euthanized Sunday after developing a medical condition. He had served with Wagner since 2006 and helped confiscate several hundred pounds of narcotics, track a murder suspect and recover a number of weapons, Plainfield Sgt. Mike Fisher said. The dog helped confiscate $1.2 million in currency, he said.

"K-9s are work horses," Fisher said. "They're willing to put their life on the line and are often even more productive than human officers."
