A typical door comes without the hole(s) for the handle hardware (and/or deadbolt), and the installer has to drill those himself. It would be a bit of an issue to take an existing door and flip it over but not that much of a problem to install it upside down from new.
I wonder if the lock has to be fitted upside down too… logic dictates that it should be seperate, but you never know with dog owners
