First of all good for you for thinking and planning ahead. There are many ways to prepare well ahead of time. I recommend several books. Your baby and Bowser, Childproofing your dog. and for the doggie behavior "pack" oriented stuff I really like the Dog Listener.
I would be happy to send you the hand outs we use for our Preparing your pup for the stork workshops. You can email me privately if you are interested.
