I feed all my dogs the dogs in the kennel and my inside dog Old Roy from wal-mart,and when the grease from our kitchen get to have a lot of particals in it we feed it to the dogs,also we cook a lot of fish at the camp and in the woods. the dogs get "ALL" of the fish grease , a couple pf cups a day with there feed.

they all are slick and shinny !!!! it works for me ; try it!
