Too much of a good thing (omega 3’s) can be bad. I would stick with fish oil, or small oily fish as you’re doing without worrying about getting too much into her system.
If you’re using capsules of oil, keep in mind oil can go rancid pretty quickly!
Is there a reason you’re feeding all, or mostly fish? If she can handle other types of meats, some grass fed beef would be great as the Omega 3 content blows the feedlot beef out of the water. Eggs, IME, are much loved and are a great skin and coat supporting addition. (A few of mine get them raw, others prefer them warmed in a skillet. They’re spoiled..!)
