I only use small amounts so no, they won’t mess up the balance. And you have a couple choices on how to incorporate fish. If you feed 2 meals a day, feed one or two meals a week of oily fish, most of what I’ve read said one, but one source was talking about dogs that seemed to need more oils and it suggested twice a week. The other way is to divide that amount up and feed some every day.
