So, back a few months ago, Waffle came down with a GI infection that resolved itself after a couple of weeks on an antibiotic.  During the course of trying to find out what was wrong, they discovered he had back pain and labeled him as having IVDD (and hip dysplasia) because he was a corgi.  But, the X-rays showed no blown disc or any real problems with his back.  They prescribed me a pain medication (Tramadol), but he has never shown any pain in his back end so I have never given any to him.  Fast forward a month or two, or three, and he was on the couch with me and I did the "test" the vets performed to see if there was any pain.  The "test" involved squeezing each vertebrae and gauging his reaction.  I got only a minor reaction out of the spot the vets had diagnosed IVDD or something like it, but it was still more of a reaction than the rest of his back.  

Tonight, I put Waffle on our kitchen table so I could photograph him and draw conformation lines as per this thread, and I noticed something curious.  Corgis are supposed to have a flat topline, and Waffle clearly doesn't.  In fact, the very crest of the rise near his butt is almost exactly where his back hurts.  Is this a coincidence, you think?  What does it mean, if not? :0  Also, here is an X-ray because I paid for it and I am going to post it in a relevant topic, darn it.  Of course, the X-ray isn't curved in the same place as the photo, and isn't even facing the same direction.
