It's not a matter of getting him to not chew, its a mtter of finding safe ok things for him to chew. They do it for specific reasons and to try to break him of that would be inccorect. Not only is it beneficial for them while they are teething it is a soothing, realxing way for them to unwind and feel comfertable. Think of their chew toys as a security blanket, especially taken away so young from it mother and litter mates. You cannot reprimand him at such a young age for chewing on the wrong things, instead exchange what he is chewing on for something that is appropriate and see if he gets the hang of it. It is also your responsibilty to not leave things lying around for him to chew on. ( sorry if I'm stating the obvious just covering all ground)
My Rory is now 18 months and her chew toys offer her comfort everyday. On road trips they are helpful and I bring her cow hoofs to friends houses incase she starts to get rambunctious I put her ina corner or outside with it and she calms down.
Chewing on specific things when they get older is also beneficial to their health because it keeps teeth clean and removes plaque. Good luck with your new pup and hide your shoes, sandals, hats, remotes, batteries, cell phones....all that good stuff!
