Post 6 & 7 might be the answer.My Schnauzer is allergic to most grains.We feed him Blue Buffalo and it seems to do the trick.Not the cheep stuff.Learn to read the labels and see what foods cause a reaction.Weather also can cause a flare up and keeping some benies on hand is a good idea.I don't like to give him the Prednisone but keep it on hand just in case.When he starts up some times he'll root a hole on his back side in no time at all.
Best of luck,It can be a life long challenge.

Added,Watch your treats as well.Some of that stuff is garbage.
