Fish oil is not primarily for skin/coat health. It helps, but the n-6s (linoleic in particular) are actually more important in that respect. Fish oil supports the immune system, heart health, and helps the body repair damage caused by oxidation during strenuous activity. It also helps brain function. DHA is vitally important to growing puppies for the proper development of their nervous system, and EPA is required to stabilize mood (it's needed to build the chemicals that tell the brain "we are happy now" and "that was enough";).
n-3s are particularly sensitive to light and ordinary oxidation. In other words, these fatty acids go stale very quickly at normal temps and oxygen levels unlike n-3s and n-9s which take longer, or need higher temps/oxygen saturations. So, unfortunately, there's no way that even extra omega-3s added to a bag of food, could possibly be present in any amount once it's bagged, warehoused, shipped, shelved, and purchased.
Plus, todays meats are pathetically low in omega-3s because they are fed grain rather than grass and grown out and slaughtered in mere months rather than living a normal lifespan. Poultry and rabbit, in fact, are mere weeks old when they are slaughtered. Even grass fed products are undersupplied with omega-3s because our soils are so depleted.
I supplement with fish oil, the best source of omega-3s for pets, plus vitamin E which ensures correct antioxidant levels are maintained in conjunction with the oil supplement. It's so easy to do I figure why take the chance? Many vets recommend it, as do veterinary nutritionists and small animal dietary specialists.
Today's children's products are supplemented with DHA, since this has become a concern among pediatric nutritionists, plus many pediatricians recommend supplementation with a fish oil product made for children (we do). If it's important enough for human doctors to take notice, I think it only stands to reason that I can improve my pet's diets with this one small addition.
