    Made skin issues worse

    By LabMom on Mar 18, 2021

    Unfortunately this product did not help my lab’s skin issues. She had a strange odor and her skin was drier. The odor went away and her skin and coat improved once I stopped giving her this oil.

    Best fish oil

    By Thomas on Mar 21, 2019

    I did not know that fish oil had to have enough EPA-DHA to be effective. I learned this from my vet recently, so the fish oil I had been using was no good and did nothing to help. This fish oil has all the right stuff.
