The amount of times a day a puppy poops can vary from puppy to puppy and how often that puppy eats during the day.
If the puppy eats more then obviously they may poop more than a puppy that doesn't eat as much.
But expect your puppy to need to poop at least 5 times per day so make sure your puppy gets outside at least 5 times per day so they can poop outside.
