Hi there, Here is an excerpt from the ASPCA's article on aggressive puppy biting ....
Taken from this page: http://www.aspca.org/site/PageServer?pagename=pets_mouthing When Mouthing Become Aggression Puppies sometimes have temper tantrums. Usually a tantrum will happen when you are making the puppy do something he doesn't want to do. This might be as benign as simply handling or restraining him. A tantrum can also occur when play escalates, much the same as when children play and one child gets upset and angry. A puppy temper tantrum involves more than playful mouthing, but it isn't always easy to tell the difference. Possible indicators that your puppy is having a tantrum include: - He may become quite stiff in his body. - He may pull his lips back to expose his teeth. - Almost always, the bites directed toward your hands will be much more painful than what he may inflicts during play. If you think your puppy is having a tantrum, it's best to take a firm hold on him, tell him, "That's enough!" and immediately carry him to a quiet, confined area, such as a small room or his crate. Leave the puppy for no more than five minutes. When you return, resume whatever you were doing with the puppy before the temper tantrum--assuming it was something the puppy needs to learn, such as how to remain still for body inspection or during grooming, or if you were attempting to teach him appropriate play behaviors Some puppies may exhibit behavior that goes beyond the basic tantrum. If you believe that your puppy is biting aggressively, you should definitely seek help from a Certified Applied Animal Behaviorist, Veterinary Behaviorist, or Certified Professional Dog Trainer.
