Why is my dog so badly behaved?!?!?!?!?

I think you should bring your dog outside everyday for 2 or 1 hour and you should tell him stop it! and train him like this everyday he will stop tell him No!!!! bad boy! and give him food or something theres a similar dog like this that always barks at me and my mom when we are going some where but is not there anymore they moved but you should really just ask the vet how to do this or say stop please no don't do that sit when he sits u say good boy and say roll over you should train him that
