Just playing with other dogs in your house or the neighbor's dog isn't enough - they need to learn to be comfortable around unfamiliar dogs too.  Dogs have different communication styles and the more dog language your puppy understands the less likely there is to be a misunderstanding between dogs.  Supervision is important when puppies play too. Shy puppies can get bullied and become fearful.

Also, at this young age a puppy is learning how to use their teeth.  We want them to learn how to inhibit their bites so that their teeth don't damage other dogs or people when they're adults.  Simply telling them "NO" when they bite won't teach them anything about jaw pressure.
