ST. LOUIS COUNTY, MN-- Another St. Louis County K-9 officer has passed away, the second in a week.
K-9 Diesel died Tuesday morning, according to a Facebook post from the Northland K9 Foundation.
Diesel was just shy of his 8th birthday and had been with the department since 2014.
According to the post, although his retirement hadn't been officially announced, Diesel had been off duty for several months due to a degenerative spinal issue.
He'd had several surgeries and was reportedly doing well, until this past weekend when he lost function in his back legs.
A trip to the vet determined he was unliklely to improve, so the department made the difficult choice to end his suffering.
His partner, Deputy Fye, called Diesel a "great partner, companion, and a huge part of what made me the K-9 Deputy that I have become."
According to the post, the pair were a great team.
Diesel deployed more than 300 times and had many notable apprehensions, including a man who'd been firing a semi-automatic rifle in a Proctor neighborhood, a drug dealer armed with a large knife, and a man who'd broken into a couple's home and held them at gun point.
Diesel was one of the first K-9s the Northland K9 Foundation helped fund in their first year. The organziation said he will forever hold a special piece of their hearts.
Last Wednesday, St. Louis County Sheriff's Office said goodbye to retired K-9 Kilo, who also died unexpectedly.
He'd been with the department for eight years.
