Some pet parents add fat to their pets’ diets with the intention of improving coat quality. Cod liver oil, vegetable oils, and animal fats are occasionally added to a pet’s food. It is true that fish oils are excellent sources of vitamin A, vitamin D, and the omega-3 fatty acids. However, both of these vitamins are toxic when fed in excess. In addition, oversupplementation with fat could result in obesity. If you feed your pet high-quality food, adding fat or oil should not be necessary. In most cases, diet is not the principal cause of poor coat quality. More probable causes of skin disorders include internal and external parasitic infections, allergies, and various hormonal imbalances.
