Rui Navarro
Rui Navarro is the founder and lead trainer behind TYR Protection Dogs and the founder of Elite Boerboels.
With more than 25 years of hands-on experience working with dogs, Rui has dedicated his career to developing stable, reliable protection dogs for real-world civilian environments.
Over the years he has bred, trained, and placed hundreds of dogs with clients around the world, building an international reputation for producing protection dogs that combine power, control, and stability.
Rui is also the author of a best-selling book on Boerboels and working-line development. His approach focuses on clear communication with the dog, strong obedience, and protection work that remains fully controlled and safe for family environments.
Together with his wife Sandra, Rui raises and develops dogs in a real home environment, ensuring the dogs are socially stable, environmentally neutral, and calm in everyday situations while remaining capable of responding when a real threat appears.
Sandra Navarro
Sandra plays an important role in the daily development and social stability of our dogs.
Her work focuses primarily on early puppy development, foundation obedience, environmental exposure, and structured socialization — helping each dog build confidence, neutrality, and calm behavior from an early age.
As a mother and a constant presence in the home environment where our dogs are raised, Sandra contributes to the natural integration of the dogs with children, daily family routines, and real-life civilian settings.
She also assists in obedience refinement and supports the protection training process, helping maintain the balance between control, structure, and social stability that defines the TYR approach.
