Most puppies go through a stage where they become very mouthy and try and bite everything. This is a very different situation to an aggressive dog that is not being playful but is trying to inflict damage. I assume your dog is just being mouthy but if it is aggressive then you should contact a professional behaviourist asap. Mouthy puppies are best handled with consistency. When the pup bites firmly say no and put it on the floor and ignore it for a minute or 2. Resume play and repeat when the pup bites. Give the puppy plenty of toys which it can bite but never encourage it to see your hand as a toy.
