We had a Siberian for a couple months. He never barked; he just howled constantly. And we could NEVER let him off the chain because he would run off.
I have a 7 ft. game fence-and my Husky is a Siberian. In all the 14+ years I’ve had her, she is never allowed alone in the yard-they are notorious doggie escape artists-just have a yearning to go find the Iditarod and run.
