Lol, you're yelling at us - are you yelling at your puppy too? If you are, then this has to stop - you can make things worse by being excited and yelling.
If he isn't obeying, he might not understand what you're asking. What have you taught him so far? If he's eliminating on the same spot, he's trained himself to go there. Use special cleaners to get the smell out, not regular stuff, like Nature's Miracle. Chewing is normal - does he have toys?
If you get into some classes with him, you'll enjoy him alot more and give him a break too. Even reading some books would help you out. Is he your first puppy?
