The act of lifting the barrels to the frame requires sweeping the barrels on nearly a 45% arc. If you can do that without sweeping something you don't want to shoot surely it is possible to raise a loaded gun safely.
Think about it, ohiosam: lifting barrels to the frame means the gun isn't locked until the muzzles are up. Lifting frame to barrels means your gun is loaded, locked and ready to fire while still pointing at the ground - where dogs can be running in unpredictable ways. That gun is then in battery throughout the entire arc from down to shooting position.
While you bring the barrels up to the action, both hands are in gunning position where you have maximum control at all times. If you lift the butt to the barrels, you have to change hand position while holding a loaded, locked gun. Which is safer?
Of course, you have a right to handle and load your gun any way you want - but I won't hunt my dog with anyone who makes a habit of pointing a loaded gun at the ground.
