Because Labradors have a specific chemical makeup, what you feed your dog can increase the lifespan and the quality of life of your beloved pet. When choosing a food, the amount of protein, fats, carbohydrates, vitamins and minerals are very important. It is also a good idea to look for dog foods with salmon oil, flax oil and canola oil, all which are great sources of omega 3. These essential fats will optimize the nutritional value of any food, and contribute to healthy skin and a healthy coat. If you are feeding your lab a well balanced dog food, it should cover all their nutritional needs, and extra vitamins and supplements should only be needed in specific situations.
