Fat is your dog's most concentrated energy source, delivering more than twice the calories per gram compared to protein or carbohydrates. But fat does far more than fuel — it is essential for absorbing fat-soluble vitamins (A, D, E, and K), maintaining a glossy coat and healthy skin, cushioning internal organs, and supporting brain function. The essential fatty acids linoleic acid (omega-6) and alpha-linolenic acid (omega-3) cannot be manufactured by your dog's body and must come from the diet. These fatty acids play critical roles in cell membrane structure, immune regulation, and inflammatory responses. A dog on a very low-fat diet will develop a dry, flaky coat, itchy skin, and may become lethargic due to insufficient energy. On the flip side, too much fat — especially sudden increases — is the leading dietary trigger for pancreatitis in dogs, a painful and potentially life-threatening inflammation of the pancreas. This makes fat a nutrient where balance truly matters.
A drizzle of salmon oil — about one teaspoon — provides roughly 4–5g of healthy fats. A medium dog (10–25kg) needs approximately 10–15g of total fat per day, which most quality commercial dog foods provide. If you add fresh foods, include moderate amounts of oily fish, eggs, or a small drizzle of fish oil rather than high-fat treats. Keep fat increases gradual to avoid digestive upset.
7.52% of daily nutrient intake
Fat / Healthy Fats makes up 7.52% of your dog's total daily nutritional requirements by weight.
Dry, dull coat that lacks its normal sheen, flaky or scaly skin, excessive shedding, slow wound healing, and susceptibility to skin infections. Young dogs may show poor growth. In severe cases, reproductive problems and impaired immune function can develop. If your dog's coat has lost its luster despite regular grooming, insufficient dietary fat is one of the first things to investigate.
Weight gain and obesity are the most common consequences of excess fat intake. More dangerously, sudden large amounts of fatty food (table scraps, fatty meat trimmings, butter) can trigger acute pancreatitis — symptoms include vomiting, abdominal pain (your dog may adopt a prayer position with front legs down and rear up), loss of appetite, and lethargy. Chronic high-fat diets can also lead to fatty liver disease and contribute to hyperlipidemia.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | medium 10-25kg | 10 | 15 | g | Adult maintenance fat requirement for a medium dog. Active dogs may need the higher end of this range. |
| Juvenile | — | 12 | 20 | g | Growing puppies need higher fat for brain development, energy, and fat-soluble vitamin absorption. |
| Pregnant / Nursing | — | 15 | 25 | g | Pregnant and nursing dogs need significantly more fat for energy-dense milk production and fetal development. |
| Senior | medium 10-25kg | 8 | 14 | g | Senior dogs with reduced activity may benefit from slightly lower fat to prevent weight gain, but should not go too low. |
