Staff Sgt. Samantha Champion, a 28th Security Forces Squadron military working dog handler, comforts MWD Lezer as his anesthetic sets in during an appointment at the veterinary clinic on Ellsworth Air Force Base, S.D., Dec. 4, 2018. Dental procedures for military working dogs require the dogs to be put under for the safety of the veterinarians and to lower the stress for the animals. (U.S. Air Force photo by Airman John Ennis)
