How to train my puppy to stop peeing all over the house?

Dogs can't be vegetarian. They're carnivores by nature. If you don't feed him right, he'll probably die soon, or the first time he gets a disease. Make him pee only out of the house, and if he pees inside the house, leave him outside for ten minutes. In fact, leave him outside for a few minutes every time he does something wrong. He won't learn anything on his own, no matter how much time it takes, and he eats anything during walks because he's not being fed right. Dogs aren't omnivores, they can't be vegetarian, or they will suffer and get sick. He spreads stuff around the house to play, but he needs to learn that he can't do that, so leave him outside for a while. The cylindrical cushion won't make him aggressive, but you should buy him a chew-toy. You shouldn't spank him, unless he doesn't learn from staying outside, but spanking him all the time WILL make him aggressive. DON'T LEAVE HIM ON THE BALCONY, HE'LL THINK HE DID SOMETHING WRONG WHEN HE DIDN'T!
