This is all really good information- thank you all!

I thought that I'd pinpointed wheat as a possible problem....and then I got home and realized that I'd looked up the wrong ingedients list online So now I'm not so sure.... (Speaking of ingredients lists: Holy fine print, Batman! How's a responsible owner supposed to do their homework?)

Thorn, your story resonated with me, and is enough anecdotal evidence for me to keep pursuing this. I'm disappointed that the vet never mentioned food issues as a potential cause for the alopecia to me....but I'm glad that my TE friends have!
