Most dogs are used to going on walks or playing fetch at the park on a daily basis, but some four-legged friends don't take a day off.
The Rapid City Police Department hosted a bi-annual training session for K-9 units this week.
Around 30 dogs and their handlers, from various law enforcement agencies, made their way to the fairgrounds to train in narcotics and patrol.
The furry crime fighters are dual-trained, narcotics search, and patrol.
All-day sessions were held throughout the week, to not only keep the dogs on their paws, but also for networking between the police department, highway patrol, and other law enforcement agencies.
Once, the K-9 are called into action, officers say they become a very valuable tool.
"As a tool of law enforcement we will have to put them in a position of danger, and potentially be harmful to the dog," said Special Operations Supervisor of the South Dakota Highway Patrol, Lt. Scott Sheldon. "But again the advantage of having that tool is that we don't move to place an officer in that same danger."
In addition, the dogs live with their handler, and even train on their off days.
"Him and I spend a lot of time together," said K-9 officer Sean Doyle. "I tend to smile like him and he smiles like me after a little bit."
Depending on each unit, a K-9s career can be between 4 to 8 years, as long as it stays healthy.
