If you watch a litter of puppies playing, you will notice that they spend much of their time
biting and grabbing each other with their mouths. This is normal puppy behavior. When
you take a puppy from the litter and into your home, the puppy will play bite and mouth
you. This is normal behavior, but needs to be modified so you and the puppy will be
happy.

The first thing to teach your new puppy is that human flesh is much more sensitive than
other puppies and that it really hurts us when they bite. This is called bite inhibition. A
puppy has very sharp teeth and a weak jaw. This means that the puppy can cause you
to be uncomfortable when mouthing or puppy biting you, but can not cause severe
damage. An adult dog has duller teeth and a powerful jaw. This means that an adult dog
can cause significant damage when biting. ANY DOG WILL BITE GIVEN THE RIGHT OR
WRONG CIRCUMSTANCES ! If a small child falls on your adult dog and sticks a finger in
the dog's eye, you should not be surprised if the dog bites. If you do a good job
teaching your puppy bite inhibition, you should get a grab and release without damage.
If you don't, you may get a hard bite with significant damage.

It is simple to teach a puppy bite inhibition. Every time the puppy touches you with its
teeth, say "OUCH!" in a harsh tone of voice. This will probably not stop the puppy from
mouthing, but over time should result in softer and gentler puppy biting.

The commands necessary to teach a puppy NOT to mouth, are easy and fun. Hold a
small handful of the puppy's dry food, say "take it" in a sweet tone of voice, and give the
puppy one piece of food. Then close the rest of the food in your hand and say "off" in
that same sweet tone of voice. When the puppy has not touched your hand for 3 to 5
seconds, say "take it" and give the puppy one piece of food. We are teaching the puppy
that "off" means not to touch. You should do this with the puppy before every meal for at
least 5 minutes.

After a couple of weeks of the above training, here is how you are going to handle
puppy biting or mouthing:

a. Unexpected mouthing (you don't know the puppy is going to mouth,
until you feel the puppy's teeth):

"OUCH!"

b. Expected mouthing (you see the puppy getting ready to mouth you):

You say "OFF" before the puppy can mouth you.

c. The puppy is mouthing you because of a desire to play. You have
to answer the question, "Do I have time to play with the puppy now ?"
If you do, then do "sit", "down", "stand" or other positive 'lure and
reward' training.
If the answer is "No, I don't have time for the puppy, right now." then you need to do a
time out (crate, or otherwise confine the puppy, so the puppy can't continue to mouth
you and get in trouble.

I believe, you will find the above much more humane than yelling at the puppy all of the
time.

The above training methods have been modified from information that I learned from Dr.
Ian Dunbar in his puppy training seminars and from his excellent video 'Sirius Puppy
Training'.
