I have this problem with my puppy. It loves to chew and bite anything
in its path. While this can be exciting, it can also become
frustrating. Imagine your puppy chewing your new Gucci shoes. uuuh!
All puppies are generally like that. Chewing everything in sight and
biting your hands. You can never be sure what they are going to be
eating next. This behaviour is typical of them because they just want
to have fun. Like little kids, they prance about. Solving a puppy's
biting habits and getting it to stop can be hard. To do this
effectively, use the ouch method. I had to use this method which I
found at http://dog-training-tips-and-resources.blogspot.com.

While you are playing with it, if it bites you, just say ouch! Dont
say this in a loud tone. Make it even. You don't want to scare it.You
want to let it know it did something wrong. Initially,it will not get
the idea. But as time goes by, when you say ouch and lock it up in
another room, or place it behind the doors, it will get the idea.

Dont despair of your puppies. They are extremely loving little kiddies
-that's what I like to call them- and most importantly, you can trust
them. Have you seen the way they look at you with love? It's
absolutely beautiful. Thank God we at least have one thing we can rely
on not to disappoint us.
