Hope your vet is able to help on Monday, interesting info about Soya I didn't know that. My pup Woody is on Eukanuba but I'm not sure if it's any good. We are going for a vet check on Tuesday, Woody is quite scratchy so I want to eliminate any obvious causes before looking in to changing his food. I look forward to your update, good luck.After researching the pero organic dog food it contains soya which can be the cause of itching and fur loss. as soy is commonly associated with food allergies in dog food.
