Yes. Salmon 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 45 g per day for an adult Border Collie. 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.

A moderately active Border Collie eats around 2.5% of body weight per day. On high-activity days (hiking, agility), increase to 3–3.5%. Scale back to 2% on rest days. Following NRC 2006 guidelines, energy requirements can vary twofold depending on exercise intensity. Adjust gradually and monitor body condition score — ribs should be palpable but not visible when you run your hand along the side.

Raw salmon MUST be frozen at -20°C for a minimum of 7 days before serving. This step eliminates the risk of Salmon Poisoning Disease (SPD), a potentially fatal condition caused by the bacterium Neorickettsia helminthoeca. Once thawed, salmon is an exceptional source of omega-3 fatty acids (EPA and DHA), beneficial for skin, coat, and joints. Following NRC 2006 guidelines, 2–3 fish meals per week cover essential fatty acid requirements.

Salmon 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, salmon keeps 2–3 months without significant nutrient loss. Pre-portion into individual bags to streamline daily meal prep and avoid repeated freeze-thaw cycles.
