For a number of years, we have been told of various things to do in order to reduce our dog's chances of getting Gastric Dilatation-Volvulus (Torsion, Twisted Gut, Bloat). One of those things was to elevate your dog's food (and water) bowls. Recent research by Purdue U has shown this to be incorrect, and that elevating your dog's bowls actually increases the chances of this life-threatening problem.

I have just taken Casey's bowls off the "elevated" and put them back at ground level.
