I am a 45 plus year Alaska resident and have studied and bred Siberian Huskies over 35 years . Having carefully selected from the most trainable, intelligent dogs with the most loving temperaments, I believe these traits make them more desirable. They are very hardy and athletic, excelling at many tasks, including sled work, backpacking and jogging partner. It must be understood that the Siberian dog must at all times be safely secured. Their high prey drive and somewhat wild linage gives them the ability to quickly be several miles away in a very few minutes . This makes it dangerous to let them roam , ever. This independent , intriguing breed can at times have their own agenda as in the past they were expected to survive on their own part of the year. This also makes them pretty contented to be away from their human companions part of their day. While they can be kept alone, being a pack oriented animal they are happier with a doggy friend. A secure enclosure and proper exercise keep them contented. The Siberian Husky was originally imported from Russia in the early 1900’s for racing purposes and they are famous for their help in the serum run by carrying lifesaving vaccine to a remote village in Alaska when airplanes could not fly. They also became famous when they won the the 408 mile All Alaska Sweepstakes Race during this same time . I believe in breeding for the Siberian Husky’s ability in harness and the physical attributes that enable them to have drive (attitude) and speed . These are attributes racing dogs must have. While you do not have to race your Siberian Husky, you should understand that they need a job and lots of exercise. They can then be a very satisfactory companion.
