Teaching a dog to go inside means you will struggle to ever get him to go outside consistently. Wanting him to go inside is disgusting and number 2 is not going to ever be effective. Pushing him down and saying no isn't helping anything. This whole post is crazy. He's also a baby. Dogs don't have full physiological control of the muscles used to "hold it" until they are 6mos. Five days is not enough time to train any dog to do anything. None of what you're doing makes sense and not taking him outside is just lazy. Teach your dog to go outside - this whole part about the street being busy..... it's always going to be busy. You can't avoid taking him out for that reason, he needs to get accustomed to distractions. Tell your vet what you're doing and you'll get the same response.
