I've put a lot of thought into "how" I want to potty train my puppy when I get it. Of course, I know that ALL this depends on what the DOG decides to do

, but ideally I hope to train it to puppy pads or a litter box (given our home and lifestyle limitations).
I also spend a lot of time at my mother's house, where I would not always be able to monitor the dog in the yard, and she will also be the one to care for the dog when we're away, so it would be very helpful to have her inside-potty trained there, as well.
If I'm able to pad/box train it in our home, will it be a simple matter of showing it where the pad/box is in another home? Are they able to make the association easily (say, like a cat might?!) that "oh, here's the thing I potty on"?
Or does it just depend on the dog?
Approx. how often does an adult dog have to pee/poop?
