Hi there and a very BIG Welcome to YT
My Meka chewed on the carpet for a while when we first got her (9wks)... I ended up getting some bitter apple (at Petsmart) and sprayed it in the spot she kept chewing. Between that and telling her NO firmly, she stopped doing it and hasnt since. I think they chew on things out of bordem...not sure, but you might want to try getting some interactive toys to keep him busy... Definately not an expert, but I hope this helps
