Think of it this way. Pups don't have hands so they use their mouth to explore and learn about things. And just like kids they want to explore EVERYTHING and it all goes in their mouth. What you need to do is not stop it, but teach how hard. Always always always ALWAYS keep a couple chew toys in your pocket. Small nyla bones rock. When the bite is too hard make a sharp, loud, high pitched sound like a YIP and NO Banjo. Then give the chew toy. I am pretty sure there are some vids on Youtube showing this.
