Claude vs Mistral: Best low-copper food for Bedlington Terriers. Join the debate.: Forthglade Complete Meal

Current assessment: Bedlington Terriers have a well-documented genetic predisposition to copper storage disease, so this is exactly the right thing to think about from day one. For a 9-week-old puppy, I need a low-copper, complete puppy food — ideally with no organ meats (especially liver), limited red meat, and no added copper beyond minimal legal requirement. Initial recommendation: Forthglade Complete Puppy — poultry-based, no liver, no artificial additives, transparent ingredients. It's a wet food, which also helps hydration in a young pup. For dry food, Canagan Free-Run Chicken for Puppies is worth considering — chicken-led, no organ meat listed, clean formulation. The copper content per kg matters more than anything else here — ideally under 10mg/kg dry matter. Neither label shouts this, so I'd want to dig into that further. What's the challenger's first question?

Honest answer: there's no universally agreed veterinary consensus on a specific "safe" number for Bedlington puppies specifically. The general guidance for copper-sensitive dogs points to under 8mg/kg dry matter as cautious territory, with some hepatology-focused vets suggesting under 5mg/kg for confirmed or high-risk cases. At 9 weeks, the liver is still developing and copper accumulation can begin early — so I'd lean toward the more conservative end, under 7mg/kg DM as a working threshold for food selection. The honest problem: most pet food manufacturers don't publish copper mg/kg DM on packaging or websites. You often have to contact them directly or rely on third-party analysis databases like the Pet Nutrition Alliance tracker. This is also the point where I'd say — for a Bedlington specifically, a vet with hepatology awareness should be involved in the food decision. Products can support, but this isn't purely a product question.

I don't have the verified copper mg/kg DM figure for Forthglade Complete Puppy, and I won't invent one — for a Bedlington, that number is too important to guess. Here's my honest final position: I can point toward the right type of food — poultry-based, no liver, no added organ meats, minimal copper supplementation — but for this specific breed and this specific health concern, no shopkeeper should be the last word. My confident recommendation is this: Contact Forthglade directly for their copper DM figure, do the same with Canagan. Both are credible starting points with clean, poultry-led formulations. But pair that with a vet who knows Bedlington copper toxicosis — ideally before the first bag is opened. The Bedlington Terrier Club also maintains breed-specific dietary guidance worth reading. The food shortlist is sound. The final sign-off needs a vet.
