It seems like for her size, upping the food was the right way to go. It seems to me that my guys and gals couldn't be begged into eating enough when they were puppies and young adults. Then, like turning on a switch, they seemed to all of the sudden start acting like I was starving them. I would check the Thyroid but rest easy that it might just be age. The nutro website has feeding charts based on activity levels and ideal body image if you want to check those out. And isn't Celiac primarily about wheat and wheat gluten? There are a lot of foods that have good fiber with all the benefits and don't have wheat or gluten. Mine uses oatmeal.

Well, it looks like, so far, switching to Acana was a very good decision. Honey has completely stopped inhaling grass, is acting much less frantic and seems to be back to her happy, content self. The itchy dog is itching less, but I am definitely going to try the organic apple cider vinegar with her. I appreciate everyones help and I am happy that they appear to be feeling better.

Regarding the celiac: Celiac is an autoimmune disease triggered by the gluten peptide in specific grains: wheat, barley, rye and depending on the person and their disease process, sometimes oats (and a few other less common grains). I react to the gluten in oats like it is wheat, barley or rye gluten.

I have celiac disease as well, so totally understand your dilemma!
For those unfamiliar, it takes only 20ppm of gluten to make someone ill. Or even those who don't get physically sick from that low level (me) you still get intestinal damage each and every time you get exposed-which can eventually lead to malabsorption issues or even cancer.
A vague idea of what 20ppm is: take a slice of bread and cut it into 5000 pieces. Just 1 of those crumbs is enough to make someone ill.
The issue with dog food is that if you get it on your hands (from feeding or getting licked) and don't wash your hands before you eat something like a sandwich, you can contaminate the sandwich with the residual gluten on your hands.

To the OP, I feed my guys Solid Gold Sun Dancer. It's not grain free, but is gluten free (it has quinoa and something else) I'll also give them Solid Gold Barking at the Moon, which is grain free. I just like the more medium protein levels of the sundancer.
