When I"m feeding the oils, fat, or lard, I'm not feeding them for the omegas in them. I'm feeding it because fat is the main energy source, and a hard working dog needs lots of fat in order to operate properly. If I'm worried about omegas and what not, I'll get that from the actual food. I'm not concerned about that coming from my fat sources, so to me, they're all the same thing. One isn't superior to the other as the dog's body assimilates it all the same except flaxseed, which is waste when using for a dog.
