Bringing home a new puppy- what gear is needed?

Might I suggest a book on "everything you need to know about your new puppy" that will give some basic outline of the potty training process and crate training methods so they start off on the right foot. You could also include a certificate for puppy cles depending on how much you want to spend. The socialization at these kinds of things is critical. Then there's vaccination certificates and/or pet insurance. Just some ideas.
