PetHonesty's Omega-3 Fish Oil is made with sardines, mackerel, anchovies and herrings, sustainably caught in the pure and clean waters off the coast of Iceland. These fish are high in Omega-3s but low in mercury and toxins and will improve your dog's joint, heart, skin, coat, brain and overall health. The high amounts of DHA, EPA and other Omega-3 fatty acids found in this 100% Natural Fish Oil for dogs will help improve any skin or joint issues your dog might be suffering from. One serving of our Omega-3 oil contains 800mg of EPA and 525mg of DHA to address stiff joints, shedding and itchy, red skin! Your dogs will love the taste of our 100% natural Omega-3 Fish Oil added to their food bowl. And you'll love that it has hardly any fishy smell! Our Omega-3 Fish Oil is naturally purified to remove the fishy odor and taste found in most fish and salmon oils for dogs.
