Omega-3s are most bioavailable (to dogs) in fish oil, which provides them in their free form, not in ALA which requires further processing before the components of EPA and DHA are available. ALA is the form that omega-3s are provided in plant oils.
You need about 1000 to 1500 mg of fish oil per 40 to 50 pounds of bady weight, typically, depending on the quality of the fish oil and its concentration, for basic maintenance (and add up to 200 mg per 60 pounds of body weight of E for that). I have a dog who gets double that, because he simply doesn't process omega-3s properly. Fish oil is safe to experiment with, up to a point - don't go to adding cups and cups of it because you'll risk pancreatitis. Just remember to add the E to help your body with the oxidization of the fat.
Omega-3s are necessary for many things that are much more "important" than skin health, so I always am concerned if I see signs that a dog isn't getting enough EFAs - or possibly is getting them in a form that is not available to them. Omega-3s are necessary for joint health, nervous system function, brain development of puppies, and hormone manufacture (not just sexual hormones, hormones regulate many other functions, as those whose dogs suffer from hypothyroidism can attest).
Be very careful messing with zinc - you can easily add too much of that. Any food with corn will have plenty of linoleic acid, and in fact most land-based meats are high in that, because they are corn-fed (lamb, beef, chicken). I do have a dog who for some reason doesn't process LA very well - I've finally been able to get him on non-corn food by simply supplementing his food with corn oil (Happy Jack Tonekote, [lol] ). Without it, he has odd, dull coat texture and doesn't shed dirt like the rest of the Border Collies.
Raw egg yolks are a great source of many skin and coat boosting nutrients, and in a form that is almost perfectly balanced and safe (especially if you include the white, cooked, and the shell, ground). When I have a rescue who is recovering from malnutrition or poor nutrition, I include a poached egg with their daily diet every day until I see significant change (about ten days), then I will continue to offer an egg every other day or so for a couple months, then they'll get a couple eggs a week with everyone else. I poach the egg because otherwise some of the good properties of the yolk are neutralized by proteins in the raw white. These proteins are made harmless when the white is cooked, however. I turn off the heat when the white turns opaque, leaving the yolk still raw (otherwise the nutrients in the yolk are largely neutralized by the heat, as well).
