Dutch breeder Leendert Saarloos crossed a male German Shepherd dog with a female European wolf.
The Saarloos Wolfdog is an incredibly complex, primitive hybrid created by crossing a German Shepherd with a European wolf. They possess deep wild instincts, immense stamina, and an incredibly striking, wolf-like appearance.
The Saarloos is a highly unpredictable, intensely pack-oriented animal. They are incredibly shy around strangers, deeply fearful of new situations, and absolutely cannot be left alone without suffering severe panic. They require an incredibly experienced owner, massive, highly secure fencing, and specialized handling. They are not suited for traditional obedience training.
