Dogs in general have no "native language" nor do they ever truly understand words as humans do. That being the case, it is still possible to teach dogs commands in any language, given the appropriate physical associations and vocal tones. Dogs understand changes in pitch better than the words themselves, so as long as you're consistent, your dog will learn.
As for the command "sit," One of the beat ways to go about it is to hold one of your hands above the dog's head with a treat inside. As your dog looks up towards that hand gently (but firmly) push the rear end of your dog down with your other hand while speaking "SIT" (or the Sioux equivalent). And reward with the treat as positive reinforcement.
