About the Trainers

Applying Experience and Practicality

At Next-Door K9 Protection Dogs, we take our dogs and the services we provide extremely serious. Each of our trainers come from either a Military K9 or Law Enforcement K9 background. Why does this matter? Glad you asked! When preparing dogs for realistic protection scenarios and capabilities, why not trust those that have seen these scenarios and dealt with it first hand in a real-life situation. These experiences help us to tailor and provide the most advantageous protection dog for your individual situation.
