The Squatty Potty thing is a position where I would most NOT be able to do what I went in for. Even the old school tiny terlit size had me too folded up. The newer ADULT sized ones allow Mother Nature to happen. But I am a Large curd kinda cheese. I think these work very well on smallish people, it was Asians who initially came up with this design. For us larger folks we need to not be knees above ears. :-)
Just in case you get all backed up trying your new raiser upper. Swap back, and see if it works out.
Love that pup.
