The house training process for puppies and new dog adoptions should start the minute you pull up in your driveway. Even if your new puppy is house trained, it needs to learn immediately where to do it's "business". The car ride and meeting a new owner should be enough excitement for any pup to have to relieve itself.
Puppies are creatures of habit and schedules, they do the same thing the same way almost everyday. A puppy relieves itself every time it finishes anything. When a dog finishes eating, sleeping, playing or walking it will go potty. It is much easier to get on your dog's natural potty schedule when beginning house training. Slowly you can get the dog closer to your schedule, but remember every dog has a different sized bladder.
