The City of Fond du Lac Police Department says Police K9 “Packo”, was put to sleep Thursday due to a sudden deteriorating health condition. The 10 ½ year old German Shepherd joined the Department in August, 2007 and was paired with Officer Ben Hardgrove. Packo was an active member of the K-9 unit until November of this year when he developed a rapidly deteriorating health condition. A police news release says Packo and officer Hardgrove were responsible for a significant number of apprehensions, arrests, and seizures of illegal drugs as well as successful tracks for suspects and missing/endangered subjects.
