Yes. Duck is a fat-rich protein that works well as the muscle-meat base (70% of the ration in classic BARF, per Dr. Billinghurst's methodology). Rotate protein sources across the week — ideally 3–4 different proteins — for complete amino-acid and micronutrient coverage. Introduce each new protein gradually over 3–5 days to monitor for any digestive sensitivity.

Aim for 10% of the daily ration as raw meaty bones — roughly 75 g per day for an adult Golden Retriever. Choose raw bones sized to the dog's jaw and never feed cooked bones (they splinter into dangerous shards). As recommended by FEDIAF, raw meaty bones provide calcium and phosphorus in a naturally balanced 1.2:1 ratio.

Large breeds like the Golden Retriever are predisposed to joint issues (dysplasia, arthritis). BARF helps naturally: raw meaty bones provide cartilage (a natural source of glucosamine and chondroitin) and oily fish delivers anti-inflammatory omega-3s. For large-breed puppies, control growth by limiting the ration to 3–4% of body weight — caloric excess accelerates too-rapid growth, as recommended by FEDIAF guidelines.

Duck is a "novel protein" — few dogs have been previously exposed to it, making it an excellent choice for food allergies or intolerances. Its fat content is higher than chicken, so adjust quantities for sedentary dogs. Duck fat is rich in monounsaturated fatty acids. According to BARF methodology (Dr. Billinghurst, 1993), novel proteins are recommended in rotation to reduce the risk of developing new sensitivities over time.

Duck is a fat-rich protein — thaw it completely in the refrigerator and serve at room temperature for better digestibility. Fats oxidize faster, so consume within 24 hours of thawing. Frozen at -18°C, duck keeps 2–3 months without significant nutrient loss. Pre-portion into individual bags to streamline daily meal prep and avoid repeated freeze-thaw cycles.
