Our Story

From the Battlefield to By Your Side


Command K9 Behavior was founded by Alexandra Nass, who served four years in the United States Army as a Military Working Dog Handler — training explosive and narcotics detection, patrol, and apprehension dogs, and participating in 13 Secret Service missions.

After returning home and relying on her own service dog through PTSD, panic disorder, and other service-connected conditions, she experienced firsthand how a properly trained dog can restore confidence and independence. That journey is the reason Command K9 Behavior exists.

Stable, Confident Temperament
