Part Dog, Part Homing Pigeon!

It's true - Minnie is Part dog, part homing pigeon. It doesn't seem to matter where she gets taken for her walk, she not only knows when she's reached the half-way point, but also the quickest route home! Maybe she's not as thick as we originally thought!!
She is also developing another of her, until now, undiscovered skills - she can clear a room in seconds with her toxic gas. She was always more of a belcher than farter, but no more aparently!! It's amazing as I can't put it down to the food she eats as she practically lives on fresh air - food is not desired!! So how does she manage to produce such foul and odourous wind?? If you know the answer to this question or more importantly the cure for the aformentioned affliction, please let me know.
