Saarloos Wolfdog

Saarloos wolfdogs are among the largest dog breeds that start with an S letter. The Saarloos Wolfdog is an interesting breed that emerged from crossing a German Shepherd with a Eurasian Gray Wolf. While these dogs retain some features of wolves in their heritage and maintain certain physical characteristics and behaviors, the Saarloos is increasingly becoming popular as an associate dog and can make a wonderful pet for individuals, families, and experienced dog owners alike.

They are caring and loving dogs, but they may not be the best choice for first-time dog owners. The Saarloos are a strong and active breed that requires a bit more attention and needs someone who understands them.  

History of the Saarloos Wolfdog  

According to recent research conducted in 2015, Saarloos Wolfdogs showed a higher genetic affinity to wolves (Canis lupus) compared to any other breed of dog. This breed was realized and named the Saarloos Wolfdog in honor of its creator in 1975. The Saarloos was also recognized by the Fédération Cynologique International (FCI) in 1981.  

The Saarloos Wolfdog was produced by a Dutch breeder named Leendert Saarloos. Saarloos was passionate about the German Shepherd breed but believed that the dog had become too domesticated. Therefore, he decided to cross the German Shepherd with the Eurasian Gray Wolf to create a dog with more “wolf-like” qualities.  

Initially, Saarloos didn’t achieve the results he had hoped for. However, he continued his work in crossbreeding to produce a fancy dog. Although Saarloos passed away in 1969, others continued the work of breeding to finalize the dog.
