I got started in K9 in the military. I spent 23 years in the military, almost exclusively in the MWD program. I retired from the military and started working for the State Patrol. I needed a job, they needed a dog trainer. I've worked about every shif you can imagine, including a few that aren't imaginable. I've worked drug, explosives, cadaver, sentry, patrol, mine/tunnel/tripwire and track dogs. My favorite thing working with dogs is taking a dog that knows no particular skill and giving it one. For a funny at a not so fun time: working a disasterous tornado area. I was working a cadaver dog. We had been in dirty ponds, mud, blown over building and really were a mess. The Coloned asked if he could ride with me to a particularly bad hit area I was heading to work the dog. when the Colonel got in my SUV, he looked at me and said; Damn David, what about the smell. I looked at the colonel, with all the seriousness I could muster and said: "Dont worry Colonel, the dog will get used to you. Well, I thought it was funny.

K-9 is one of the most rewarding positions a person can have the priviledge to earn in a career. I am on my 9th year of being on leash and still have to pinch myself everyday to realize what I am getting paid to do.
