This formula is very rich in omega 3 and 6 fatty acids producing a healthy skin and coat for your dog. Single source protein (fish) and carbohydrates (potatoes) means this is one of the most simple, easily digestible, grain free diet available in the market today. FirstMate Pacific Ocean Fish Formula is great for rotation or elimination diets. All FirstMate formulations are manufactured at their plant located in Chilliwack B.C. Canada with care.
