Hi ramroxy –
If the allergy issues didn’t start until you moved and she was eating the same food prior, I’d be more inclined to assume the allergies are environmental and not food related.
Have you done or considered doing a food elimination trial? It’d kind of a tedious thing to do but it would be the only accurate way to determine what ingredients (if any) are causing the symptoms. It involves feeding a novel protein and starch to your dog for a period of time and gradually adding in new ingredients, monitoring the reaction to each, to determine what ingredients (if any) cause a reaction.
As far as limited ingredient foods go, try to find a food that features a single novel protein and is free of common allergens such as corn, wheat, soy and dairy. Acana singles are good and I wouldn’t be concerned about the avocado in Avoderm – the fruit and oil (which is what is used in dog food) is not toxic, it’s the bark, skin, pit and leaves that are toxic. Some other good hypoallergenic foods are: Nature’s Variety Limited Ingredient Diet, The Honest Kitchen, Grandma Lucy’s, Addiction, California Natural Grain-Free, Artemis SOS and Artemis Osupure.
