Yes. Lamb 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 188 g per day for an adult Saint Bernard. 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 Saint Bernard 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.

Lamb is one of the best proteins for elimination diets because it is rarely allergenic. Its fat content is high — trim surface fat for sedentary or overweight dogs. Lamb ribs make excellent raw meaty bones for small and medium breeds. Lamb heart and kidneys are nutrient-dense organs. Following NRC 2006 guidelines, lamb provides excellent coverage for zinc and heme iron requirements.

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