Dietary fats and fatty acids play a crucial role in a dog’s nutrition. Fats provide energy, aid in fat-soluble vitamin absorption, modulate inflammation, act as a precursor to important substances, and serve structural roles in cell membranes. Dogs require essential fatty acids, including omega-6 and omega-3 fatty acids, in their diet because they cannot produce these on their own. Essential fatty acids are necessary for healthy skin and coat, reproductive function, growth, and overall well-being. Sources of essential fatty acids for dogs include plant-based oils for omega-6 fatty acids and fish oil for omega-3 fatty acids. It is important to ensure that pet food provides these essential fatty acids in appropriate amounts to meet a dog’s nutritional needs.
