Stop Dog Biting and Nipping
  
  Biting and nipping can be normal puppy behavior, and 
  to other dogs, with their thick furry coats, it isn't a 
  problem. Puppies, like most babies, like to try 
  everything out in their mouths, sometimes including 
  even your hand, leg or other body parts. 
  But as your pup's human, you have to deal with this 
  issue from the beginning or it can create long term problems.
  
  For the most part dogs nip as a part of play. This is a
  natural behavior they use to play with their doggie friends
  and sometimes they don't realize that you aren't as into it
  as their canine pals might be.
  
  This is especially true if your puppy is of a breed that was
  designed for herding or guarding, such as shepherds, cattle
  dogs or bulldogs. Their ancestors were bred for many
  generations to use their mouths to manipulate their
  environment, the way we use our hands.
  
  So it is a good idea to redirect this behavior from the very
  beginning, even if your young puppy's nips seem funny and
  not painful, and not let your dog get into the habit of
  thinking you or other family members are chew toys. As with
  any type of training, you want to stop this problem behavior
  and redirect it to positive behavior whenever you see it.
  
  One of the best redirects you can use for a nipping puppy is
  a chew toy of its own. Praise the dog when you see it
  chewing or biting appropriate things. When it bites
  forbidden things give a sharp "No" and re-direct the puppy
  to its toy.
  
  When a dog is going through this phase it is a good idea not
  to play games like tug of war or other rough games that
  require a lot of biting. This can encourage the exact
  behavior you are trying to curb.
  
  Another method some people claim has worked for them is to
  act injured. When your puppy gives you a little nip or bite
  yell "Ouch!" to let it know it has hurt you. Then stop
  playing with the dog. It will start to get the idea that if
  it bites, playtime will be over.
  
  Dealing with biting and nipping is especially important if
  you have little ones in the house. Little nips that may seem
  like no big deal to us could be much worse on a small
  child's sensitive skin and can even lead to the child's
  fearing all dogs. So work to curb this behavior as soon as
  it starts in order to keep everyone safe and have a well
  mannered pup.
