Meet the protection dog trainers behind TYR
Rui Navarro
Rui Navarro is the founder and lead trainer of TYR Protection Dogs, and the founder of Elite Boerboels.
With more than 25 years of hands-on experience with dogs, Rui has spent his career developing stable, reliable German Shepherd protection dogs for real-world civilian life.
He has bred, trained and placed hundreds of dogs with clients around the world.
Rui is also the author of a best-selling book on Boerboels and working-line development. His approach is built on clear communication with the dog, strong obedience and protection work that stays fully controlled and safe for family life.
Together with his wife Sandra, Rui raises the dogs in a real home. They grow up socially stable, neutral in new places and calm in everyday life, and they can still respond when a real threat appears.
When you enquire, you speak with Rui directly. Every conversation is private.
Sandra Navarro
Sandra plays a central role in the daily development and social stability of our dogs.
She focuses on early puppy development, foundation obedience and structured socialization. This helps each dog grow up confident, neutral and calm.
Sandra is a mother and is at home with the dogs every day. Through her, our dogs learn early to live with children and with normal family routines.
She also helps refine obedience and supports the protection training. Her work keeps the balance between control and social stability that defines the TYR approach.
