I think it's fine
As above, wheat may be a common allergy-causing food item, but not every dog suffers allergies - and if yours doesn't, he doesn't.
I just wouldn't give it daily, is all. 2-3 times a week would be quite sufficient, and help to diminish the "constant exposure" factor that so often leads to allergies. And if those oils happened to come separately, I'd probably choose to buy them separately and rotate between them (thereby further diminishing the "constant exposure" thing).
