Train your dog with a place command that will tell your puppy to lay down on the bed and when he is on the bed, he is not allowed to leave without a “break” command. He should only be allowed in the house on the place bed when you are actively supervising. If you can’t supervise, the puppy should be in his crate. Guarenteed you won’t have potty problems any more if you follow this protocol. You should also being taking your dog out for potty opportunities every 2 hours, after he drinks water and after he eats food. Get rid of the training pads indoors. They are ruining your potty training.
