I don't want another allergy (skin) dog, royal PITA, though my worst one was a mixed breed. I don't know about the inheritance factor, I don't think it is usually a simple inheritance and can just "pop up". I just don't feel comfortable breeding a dog with real, confirmed, chronic allergies that affect daily living, whether it be a special diet or the need for medication. I would not personally breed one and I would hope stud owners are honest enough when I ask them about such things.
