Samoyeds have a long history of being the working dogs of the Samoyed people who used them for herding rain deer and sledding, and of course staying warm during those cold nights.
Here are some great videos and photos of Samoyeds reliving their heritage in sledding practice and competitions throughout the world.
Here's a great first person view of being pulled through the thick snow in Germany by a group of beautiful Samoyeds.
If you'd like to learn some more about competitive Samoyed sledding take a look at this page which discusses the various types of sledding you can do with your Samoyed
Of course it's not always competitive sledding which Samoyed's get to take part in. Sometimes they have some higher profile sledding to take care of.
