This is a specific conversation about Dog food — finding the right one — ask about yours and get one honest answer for your exact situation.

A working Border Collie on a farm is a completely different animal to a pet Border Collie doing weekend walks — the caloric and nutritional demand is genuinely in a different league. Choosing dog food is complicated at the best of times because the right answer depends on age, size, breed, and health, and the most expensive or most marketed options aren't always the best fit. That said, for a high-output working dog, getting the energy density right really does matter. Tell me a bit more: how old is your dog and what breed, are there any health issues or sensitivities I should know about, and what are you currently feeding them?
She's a 5-year-old Border Collie, fit and healthy, no known sensitivities. She's out working sheep on the farm most of the day — easily 6 to 8 hours of real activity. Currently on a mid-range dry kibble, I think it's Pedigree Adult. She eats a lot of it but still looks a bit lean.

That tells me a lot. Pedigree Adult is formulated for average adult maintenance — it's not designed for a dog burning the kind of calories your girl is. The protein and fat percentages are too low for sustained working output, which is why she's eating large volumes but still running lean. You're essentially asking a mid-grade fuel to power a performance engine. What I'd want for her is a food with protein north of 38% and fat around 18–20%, with a high meat inclusion and minimal filler. Before I give you a specific recommendation — is she fed once or twice a day, and is there any budget ceiling I should keep in mind?
Fed twice a day. Budget isn't a huge constraint — I'd rather spend more and feed less volume if it actually works.

Perfect, that's exactly the right mindset for a working dog. My recommendation is Orijen Original dry dog food. It's a biologically appropriate kibble with around 85% quality animal ingredients — chicken, turkey, fish — and delivers roughly 38% protein and 18% fat. For a dog doing 6–8 hours of real work daily, the calorie density means you'll feed less volume than her current food, she'll absorb more of what she eats, and you should start seeing her fill out properly within a few weeks. It's widely available on Amazon UK in 2kg, 6kg, and 11.4kg bags — the 11.4kg is the best value for a dog her size. Transition slowly over 10–14 days to avoid any digestive upset from the big step up in richness.
That sounds promising. How much should I actually be feeding her compared to what she's on now?

A typical active 20kg Border Collie on Pedigree Adult might be eating 400–450g a day just to maintain weight. On Orijen, because the caloric density is significantly higher, you'd likely start at around 280–320g daily and adjust from there based on body condition. The goal is to see a light covering over her ribs — you shouldn't be able to see them, but you should be able to feel them easily. Give it 3–4 weeks at that level, check her condition, and nudge the amount up or down by 10% accordingly. Working dogs also sometimes need a bit more on heavy days and less on rest days, so it's worth paying attention to her schedule.
Really helpful, thank you. I'll give it a try.

Good luck with it — she sounds like a seriously hard-working dog and she deserves a food that keeps up with her. If after a month she's still looking lean despite hitting the right quantities, it's worth a quick vet check just to rule out anything like a worm burden or thyroid issue, though that's unlikely given she's otherwise fit and healthy. Orijen is a solid long-term choice for a dog like her.
