I just picked up a 6lb bag of the whitefish and sweet potatoe and the treats to go with it. I'm going to start switching Cincy over tonight and see how it goes.

The vet did give us a different antihistamine to try and that seems to be helping a lot with the itching. We only got 10 days worth, so by the time we get her completely switched over we will be out of the meds and can see more clearly if the food is helping. If it doesn't, I think we may try the blood test and skip the Z/d. Ralph and I need to talk about it some more though.
