This is a behavior that is normally addressed by momma dog....which is another reason to not purchase puppies under 14-16 weeks old....these are all lessons that momma dog teaches her babies, and she will do a much better job of it than a human surrogate will do.
Patience and understanding on your part, that this is normal behavior for a puppy....this is the only way they can explore and get a feel for their environment....just like human babies, everything goes into the mouth. This is also how teething pain is relieved, again as in human babies....gnawing, chewing, gumming, sucking on, etc, etc, etc.... Understanding age development in puppies and what behavior is to be expected, and why and how it is "normal behavior" and how it can be redirected, is most productive. Some behaviors can not and should not be expected to be corrected because that is the behavior for that particular age bracket, and just like you can not expected to "teach or train" a human baby not to suck when it is 8 weeks old, there are behaviors that can not be "trained" from happening in a puppy....which is why it is so important for people to understand what is NORMAL behavior at any given age, in their puppy. Depriving or punishing or correcting "normal, expected behavior" in a puppy, will do nothing more than cause permanent behavioral issues as the puppy ages.

I wish new owners would become thoroughly educated about what is NORMAL behavior at any given age, for a puppy, before trying to correct or eradicate such behavior in an underage baby. You have to be aware what is normal behavior for that age, and then work with the behavior until the baby gets through that stage. If you have a puppy that has been removed too early from its momma, who would be doing the teaching of these lessons, then it is imperative that you are knowledgable about the normal developmental progress of any puppy at any given age, and learn how to deeal with that behavior as momma dog would be doing.....otherwise, you will probably have a puppy that will exhibit behaviors that reflect that "early childhood deprivation". You can not teach a human baby not to suck on a nipple, any more than you can teach an underage puppy not to mouth and chew and "bite" on items it comes in contact with....that is normal behavior, that is how both species' babies learn about existing, about living, about learning.....you must know what should be considered acceptable degrees of biting, chewing, etc and at what age these behaviors can be corrected and by what measure.
