But then there's always that nagging question: If future studies confirm that marine omega-3 and omega-6 fatty acids do build a faster, better canine learner with keener vision--is this truly to the owner's benefit?

Many researchers think a higher intake of omega-3 fatty acids (found in meats and dairy products from grass-fed animals, flaxseed, seafood, walnuts and some leafy greens) reduces the risk of heart disease and, potentially, cancer by offsetting the too-high intake of omega-6 fatty acids in the contemporary U.
