Chattanooga – The Chattanooga Police Department is mourning the loss of K-9 Buck, a two-year-old Labrador who passed away from medical complications earlier this week. His death follows closely on the heels of K-9 Diesel’s, a three-year-old German shepherd who was euthanized just days earlier after sustaining severe injuries.
K-9 Buck died on Wednesday, only a week after K-9 Diesel’s passing on September 17. Buck displayed signs of gastrointestinal issues and lethargy the day prior, prompting his handler, Master Police Officer Lucas Timmons, to seek veterinary assistance. An initial examination by Buck’s primary veterinarian revealed significant abnormalities that required a referral to a specialist.
Upon further evaluation, K-9 Buck was diagnosed with septic peritonitis, which escalated to Disseminated Intravascular Coagulation (DIC), a life-threatening condition with a high mortality rate. Despite all possible medical interventions, K-9 Buck was unable to survive the serious complications associated with his diagnosis.
K-9 Buck was born on June 17, 2021, and joined the Chattanooga Police Department in August 2022. He was trained in explosives and firearms detection, contributing to numerous safety sweeps and investigations related to gun crimes. His role extended beyond professional duties, as K-9 Buck lived with Officer Timmons and his family, participating in family vacations and recreational activities like swimming.
Chattanooga Police Chief John Chambers expressed deep sorrow over the loss of two K-9s in such a short timeframe. The department honored both K-9 Buck and K-9 Diesel for their invaluable service and contributions to the community. The close bond between police dogs and their handlers, exemplified by the relationships built during their time together, has been highlighted in the wake of these unfortunate events.
The Chattanooga Police Department showed appreciation for the veterinary teams involved for their efforts in caring for both K-9s during their medical crises. The loss of Buck and Diesel underscores the profound emotional impact such losses have not only on their handlers but also on the department and the community they serve.
