I was interested to see that the Soviets had actually created a breed, given that the Soviet state did its best to destroy dog breeds that, by their very existence, challenged Communist ideology and Russian nationalism. The Siberian Husky and Alaskan Malamute were originally bred by native Siberian peoples, the husky by the Chukchi "Indians" and the malamute by the people of the same name—Mahlemut. Tragically, both were all but completely eliminated in their land of origin by a deliberate Soviet policy of "assimilating" (read eradicating) native cultures.
Fortunately, however, Americans with an interest in dogsledding had "discovered" huskies and malamutes a few decades earlier, and had imported some of the dogs to the States. America became an "ark" for those breeds when the USSR instituted its genocidal policies.
I'll write more later on sled dogs, including sibes, mals, and the Alaskan husky.
