WRIGHT COUNTY - Saber, a police dog with the Wright County Sheriff's Office for nine years, passed away suddenly on Thursday night.

"It is with heavy hearts, we regrettably report, the sudden passing of K-9 Saber," The Wright County Sheriff's Office Facebook Page says. Saber collapsed while working with his handler, Deputy Cotton, and was rushed to the vet.

It was determined he was bleeding internally from a ruptured tumor and little could be done to save his life.

Saber was scheduled to be retired from service next Friday.

Saber began his patrol career with the Wright County Sheriff’s Office in the spring of 2007. He twice received case of the quarter for locating suspects in Carver County and Monticello, and case of the year in 2014 through the United States Police Canine Association.

"He was an asset to the patrol division and will be missed by his handlers," The Sheriff's Office says.
