True Samoyed's are willful and they do have a mind to do as they please but they are certainly not untrainable. The way to go is start as you mean to go on. On a personal level I start training mine when they are small puppies, as young as 9 weeks. And I do believe if you have to teach any dog one thing it should be his/her name and the command to come. 
"So how is it taught"
You can start from 8 weeks old. Its very easy when your puppy is at home playing, just simply throw a toy, which your lively bouncy pup will go chasing after and grab, then clap your hands and say " Puppy come"(obviously using your pups name). When they come back to you, praise them and take the toy and replace with a treat. This a great game for your puppy, and they will enjoy it. It also gives you valuable time spent building rapport with your pup too, which is essential if you want to work or show them. So by the time your pup is ready to go for walks in the park, your pup will have learned that when you call their name if they return they will be rewarded for coming back to you.
If you want to show your dog its best to teach the stand position first. Standing your puppy just for a few seconds commanding stand and giving a titbit, soon gets them into the habit.
But there is no reason why you can't teach a show dog to sit or lay down.
Titbit's work wonders for training your pup, and most Samoyed's love their food. But if they are a dog who really isn't into food then you can use a favorite toy.
When you get your new puppy lots of people will probably give you all sorts of help and training advice. And I think from all the information you gather you will find your own way of training, and if it works for you than stick with it.
SO GOOD LUCK
