6 year old dog's behavior problems?

my dog is 6 years old and has never had a problem with nights, but lately has been doing strange things at night … He started by pee and poop every night for a week and got tired of it, so I tied him to a door, then he started scratching the carpet and moaning all night, and then the last 3 nights that has started chewing the wood work to the point where your mouth begins to bleeding, there is no way to get him to stop, help please? if help is a Shiba Inu and when we tie it gave no leash at all, just enough to establish

What about you to your veterinarian for advice, and why did they tie the dogs hate it,
