We recently got a new puppy, an indoor dog named Copper. He’s the sweetest little dachshund, but he can also be a pain to our much older dog, Bud. I’d forgotten how long it takes to housebreak a puppy. He’s done fairly well, but I’m ready for him to learn that he can go through the doggy door without me and take care of his business outside whenever he needs to. This is also the first time I’ve had two dogs trying to get along, especially one so young and the other so old.
