• If you’ve found an orphan puppy, you won’t know exactly how old he is.

    But you need to make an educated guess so you can determine the kind of care he’ll need. A two-day old puppy needs a completely different of care than a three week old. Once you’ve figured out his age, you’ll know if you need to stimulate him to potty or start housebreaking him.
