If your dog is otherwise fit and healthy and there are no worrying signs, like weight loss, poor appetite, excessive thirst, excercise intolerance, seizures etc he most likely is fine and these two episodes were just due to very deep sleep. However, please, report these episodes to your local vets when you see them next time. They will fully examine your dog (including neurological examination) to make sure that there is nothing to worry about.
