Origin and history
Where the breed comes from
The Saarloos Wolfdog was created in the Netherlands in the 1930s by Dutch breeder Leendert Saarloos. He crossed a German Shepherd Dog with a female Eurasian wolf, aiming to produce a more natural and robust working dog. The breed was officially recognized by the Dutch Kennel Club in 1975. However, its recognition status varies by registry, and it is not universally recognized. The breed's history is rooted in this specific crossbreeding effort, but details about its early development beyond this are limited.
