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 kind 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.
Please remember that this chart is only general guide. Every puppy matures at a different rate. Larger breed dogs tend to mature earlier than small dogs.
