Thanks for posting this. I am experimenting with a free wheat-free diet right now also.
Oddly enough, one of my dogs was just diagnosed as being allergic to wheat, and I’m trying to figure out a gluten free diet for her-—there is gluten free dry food for dogs, but there’s gluten in a lot of other things like milk bones, etc, and most “treats” that we have been giving her.
I wouldn't care but it is annoying how much shelf space gets allocated to gluten free stuff that really tastes like crap. Even if you think you are sensitive to wheat (whatever that means), it isn't worth eating garbage for the rest of your life.
