Samoyeds are large, long-haired white dogs from Siberia. They were bred to herd reindeer, to pull sleds and to keep their owners warm at night. They are a very energetic breed and need lots of space and regular exercise or they will get bored and destructive. They are friendly dogs and don't make very good guard dogs. One of their interesting features is they don't have a 'doggy' smell and they don't shed much, so are classed as 'hypoallergenic'.
