Like others have said, Siberian Huskies and German Shepherds are VERY different.
Siberian Huskies are high energy, high drive, super friendly dogs that love everyone! They have intense prey drive and therefore can;t be trusted around small animals (this includes little dogs too!!!) and livestock. Expect to be challenged throughout the dog''s life as they are quite dominant. Don;t expect a push-button dog because they are very stubborn and independent. Sometimes when I call Ronan in he stand there with a very blank expression on his face just staring. He knows the command "come" no questions about that, he simply does not care. The fact that they don''t take commands to well isnt a question of dominance though some misinterpret it as such, it''s simply the independence shining through.
I hope you enjoy 1-2hr walks daily because that is what these guys need. The faster the pace the better for them. When summer time comes its ok to reduce this and decrease the pace simply because of the heat but they still have to get out there. Also they need training to keep their minds busy. They do love to learn once you find their motivation and they can be trained just takes extra effort with them.
If their excercise need aren;t met they will find an outlet for their energy in less desirable ways...AKA completely gutting your house and ripping everything to shreds. Remember, a tired Sibe is a good Sibe.
A Sibe from show lines will have that look you see most often in the media, the stocky, thick look like the dogs in 8 Below and Snow Dogs. These guys are a little calmer and laid back but still high energy. A Sibe from working lines would be a little rangy-er and more high energy. They''re constantly on the go and super fast too!
Remember, Sibes can NOT be trusted off leash in an unfenced area and for complete peace fo mind they must have a 6ft fence or be tied up. When they get loose they run fast and far whether you;''re along for the ride or not. I had a mushing friend lose two dogs and the next day they were a few hours drive away!!!! They ran all day and all night before they were caught and when he did pick them up they were ready for more!
