will the dogs ever learn

saturday night my dogs had me in stitches  . my dad decided he wanted the double patio doors lowered so it would make life easier for him for when he ends up in a wheel chair  he cant do the work so we paid a neighbour to do it . the doors are now turned the other way round so instead of going out the right side we now go out the left and omggggggggg will the dogs ever get the hang of it  every  time i have gone to let them out they are stratching at the wrong end on the inside to get out and vice versa to be let back in and they look at me as if to say what u doing that end of the room
