Rui Navarro is the founder and lead trainer behind TYR Protection Dogs.
With over 15 years of professional breeding and development experience and more than 30 years working with dogs his focus is clear: real-world civilian protection built on control, stability and discernment.
Author of a best-selling book on working-line development, Rui has placed over 700 dogs worldwide and built an international reputation for producing stable, capable, and reliable working dogs.
Every protection dog is developed under the Real Defense Protocol, prioritizing clear threat assessment, absolute handler control, and seamless integration into family life.
Together with his wife, Rui raises and develops dogs in a real home environment, ensuring social neutrality, environmental stability, and calm behavior outside of threat scenarios.

Santa Freitas plays a key role in the daily development and social integration of our dogs.
She focuses primarily on puppy foundation work, early obedience, environmental exposure, and structured socialization — ensuring each dog develops stability, neutrality, and confidence from an early stage.
As a mother and active presence in the home environment where our dogs are raised, Santa contributes to the natural integration of dogs with children, family routines, and real-life civilian settings.
She also assists in obedience refinement and supports the protection training process, helping maintain balance between control, structure, and social stability.
