I totally agree with everyone, a reputable trainer is in order. All puppies should have at the very least 2 sessions. It not only helps teach the puppies but it will help the owners learn the correct way to handle the puppy and will also socialize the puppy with other dogs, which is very important.
Good luck with your little sweetheart.
