It's a very natural and normal thing for puppies when they bite and chew on things.
Puppies will normally grow out of the biting and chewing on things stage after 6 months of age.
If the puppy is still chewing on things and biting after 6 months of age to a year then the behavior needs to be corrected.
But usually nothing needs to be done to get the biting and chewing to stop since most normal puppies grow out of the biting and chewing by 6 months of age.
