Exactly what spixie33 said; is what I didn't have time to write out yesterday!!
I didn't read the linked article; but I couldn't do a bare bum training. I need the security of a pair of undies, at least! It's minimal, but still... Not to mention, does this bare bum get to sit on my couches, chairs, and try to climb up in my lap, as well as sit on toys, etc in the playroom? Ick... LoL.
