I never had to deal with that with Morgan, he never chewed, but my little Yorkie, Bailey, is now about 4 months old, is chewing alot, not on furniture, thank goodness or anything like that, (he did like my slippers and sneakers at first lol). I have A LOT of chew toys for him so he wont' get any bright ideas to chew on the other things. As long as he sticks with the chew toys, I don't care if he chews forever! lol
my big dog liked to chew on stuff. it was soo annoying!!! i feel your pain. i basically bittered apple everything 'inappropriate' to chew twice a day. till he didnt want to try to chew it. and i gave them bully sticks. that stuff saved my life. its a little expensive--but malts dont chew it up that quickly. it smells a little nasty--bully sticks or pizzle sticks should help you out a lot.
i had a dog who chewed everything...a whole sofa....he never stopped chewing but we got him tons of toys adn it seemed so long as he had something more intresting ot chew on he stayed away from my stuff
