A retired bomb-sniffing dog who worked with the University of Illinois police has died at the age of 12.
UI K-9 Officer Troy Chew says his longtime four-legged partner, Nala, was euthanized last week. She helped him patrol university athletic events and check out potentially explosive packages for 10 years. Nala retired in August due to a nerve condition that caused her to lose feeling in her hind legs and had since been living as a pet in the Chew home.
Chew tells The News-Gazette (http://bit.ly/1yTrNSl ) putting Nala to sleep was the hardest thing he's ever had to do.
Nala was the first bomb-sniffing dog employed by the department. She came to UI as a 2-year-old dog who was already trained and taking commands from Chew in Dutch.
