1) If you didn't consider yourself a whiner before, you'll be printing yourself an official badge by the end of your struggle
2) There is not necessarily an end to your struggle..the amorphous being that is your horse might just keep it interesting and keep changing shape FOREVER. See #1
3) If you ever thought that a horse care/use question had perhaps too many answers, too much misinformation is out there, and wouldn't it be nice to just read one page that says This Is Truth, well, you've really arrived now. See #1
After months of obsess-change saddles-and repeat over the ever present dry spots behind Scrappy's wither where he had shed out bald in spring, a couple of reliable sources just recently put a bug in my ear and then I happened upon reading ex Ortho-flex guy Len Brown's site, essentially confirming what I'd been hearing. There's quite an eyeful there for reading if you can look past the very questionable site design; it's worth checking out at your leisure but here's the particular nugget I'm referencing:
" Once skin is repeatedly damaged do not expect dry areas to immediately start sweating just because you removed the pressure at that spot.
Those dry spots on the withers may be permanent or not sweat for months after rectifying the initial saddling problems. AS I SAY ON MY WEBSITE: "BRING ALONG A CRYSTAL BALL IF YOU ARE INTO READING DRY SPOTS". RECCOMMENDATION: Palpate your horse for soreness every time before [and after] you saddle up and forget chasing every dry spot."
