Storm is a 12 week old Alaskan Malamute and most of the time he is so gentle and loving, but when he is overtired he gets very nippy and growly. Yelping and saying no just makes him worse, I have found giving him "time out" in his crate for 5 mins and ignoring him while he is in there seems to work to calm him down.
My father in law has not helped by "tapping" Storm on the nose when he gets like this, despite me telling him not to
I think the whole family has to be consistant in their methods of handling nipping puppies or the poor puppy will just be confused
