To be a K9 Officer you must be very physically fit. but You don't have to go to college to become a Police officer? But you have to be atleast 19 when you finish your time at the Depo. Anyways, You have to go to Police Depo. Search on Google where you live and where the nearest Police Depo is. You then go there and train for 6 months and then you're a Police officer! Then when you get to the Depo just tell them you want to be a K9 Officer.
