If you are like most pet owners, you want to give your pet the very best care possible. While you may buy the best pet food available, it still may not provide all the nutrition your pet needs. For centuries, canine and feline diets consisted of natural and unprocessed foods rich in Omega-3 fatty acids derived from fish, algae, and plants. The health-promoting Omega-3 fatty acids found in fish oil are EPA and DHA. They are important for supporting healthy skin, coat, joints, brain, heart, and eyes, as well as your pet?s energy level. While research indicates that a ratio of Omega-6 to Omega-3 of 5:1 to 10:1 is optimal for dogs, many pet foods contain primarily Omega-6 fatty acids from vegetable oils. This results in a highly unbalanced ratio dominated by Omega-6 fatty acids. Some pet diets may include Omega-3 fatty acids. However, virtually none include satisfactory amounts of the most important Omega-3 fatty acids, EPA and DHA. In line with pet recommendations in Scandinavia, it is important to give your pet quality fish oil every day.
