For what it’s worth, I’ve always fed cheese to my dogs. Have one now with SEVERE digestive issues who can hardly tolerate anything, but cheese and hard boiled eggs are the only protein sources that never cause him gastronomic distress. I also used to mix in evaporated milk with baby cereal for my puppies, and frequently give yogurt to my adults. Never had a single issue with dairy and think it would depend more on an intolerance with the individual dog than with any ingredients in the cheese itself.
