Lab pups love to chew. Bitter Apple found in pet stores can be put on items you don't want him to chew on or a hot sauce though it might stain some items. They will mostly grow out of it. I would kennel him when you can't keep an eye on him. when he does chew on something you don't want him to tell him NO in a loud voice take it away and give him a chew toy instead. My lab still likes the furry stuff animals.
