We've upgraded our alaskan salmon oil recipe kibble topper to pack in even more nutrition without changing the same fresh fish aroma and taste that dogs love. By blending in wild caught alaskan pollock oil with wild caught alaskansalmon oil, our new kibble topper delivers more epa, more dha, and more omega 3 fatty acids than before. And, even though pollock oil is more expensive than salmon oil, we kept the price same. We also continue to use only wild caught fish that are harvested in a certified sustainable manner and then make the oil in the u.S.A. With no artificial flavors.
