Finding the right brand of puppy litter for the newest member of your household is the easy part. Not all dog owners choose the puppy litter route, as many find it just as convenient to take the puppy outside once the puppy is old enough to begin roaming about the house.Periodic trips outside are not a lot of fun if one lives in a high rise apartment or when the weather is particularly nasty, and puppy wants to take his or her own sweet time while you stand there with rain dripping down your nose. Still, having a grown dog, or even a puppy, that has been trained to conduct business out of doors is usually seen as an improvement over having to periodically empty and refill a litter box.
