I know some small dogs are trained to use paper, but I haven't heard about using a litter box. The problem is if you are thinking of getting puppies, you have to be available to train them to use the paper just as you would to get them to go outside. Taking on more than one puppy at a time would be a significant challenge. There are other issues with raising a puppy other than simply providing a place for them to *go* and these issues require considerable supervision. I would strongly suggest a grown dog for someone in your situation.
