This is a specific conversation about Raw dog food — what to know before you start — ask about yours and get one honest answer for your exact situation.

A Tibetan Mastiff on raw — that's a serious undertaking given the sheer volume of food a dog that size needs every day. Raw feeding done well can be excellent for a breed like this, but done badly it creates nutritional gaps that cause real harm over time, and the difference is balance and sourcing. Before I point you toward the most cost-effective route, can you tell me roughly how much your dog weighs, whether you've fed raw before, and whether you're set on a ready-made complete option or open to bulk DIY? For a very large dog, the answer to that last question changes the maths significantly.
He's about 68kg. Never done raw before, a bit nervous about getting the balance wrong, so I'd rather start with a complete ready-made. Main thing is keeping the cost down — we go through a lot of food.

That's exactly the right instinct for a first-timer — complete ready-made means the calcium-to-phosphorus ratio, organ content, and bone inclusion are already sorted, so you're not guessing. At 68kg, he'll need roughly 1.4–1.7kg of raw per day at a 2–2.5% body weight feeding rate, which is where cost really bites. The format that stretches your budget furthest with completes is bulk frozen blocks rather than small individual portions. Can I ask — do you have decent freezer space, and are you able to order in bulk, say a 10–15kg delivery at a time?
Yes, we've got a chest freezer in the garage specifically for dog food. Happy to buy in bulk.

Perfect — that chest freezer changes everything for you. My recommendation is Cotswold RAW Complete & Balanced frozen raw mince, bought in their larger bulk boxes. It's a genuinely complete 80/10/10 formulation — 80% meat, 10% bone, 10% offal — with added vitamins and minerals so it meets nutritional requirements without you needing to supplement. For a dog your size, the cost per kilogram is meaningfully lower than portioned alternatives, and the quality is consistent enough that you're not taking risks with a nutritionally vulnerable giant breed. They offer a range of proteins — chicken is the cheapest entry point, and rotating with turkey or lamb every few weeks is easy once you're in the rhythm. Start on one protein for the first two to three weeks while his gut adjusts, then you can introduce variety.
How does the cost actually compare to a decent kibble for a dog this size?
inparticular.ai
It's more expensive than mid-range kibble, I won't pretend otherwise. A large-breed kibble might cost you £80–£100 a month for a 68kg dog; Cotswold RAW in bulk will likely run £130–£160 depending on protein choice and any promotions. But there are two things worth keeping in mind: first, raw-fed dogs often produce significantly less waste and many owners report better coat condition and joint health, which can offset vet costs over time — relevant for a Tibetan Mastiff given the breed's tendency toward joint issues. Second, you're already set up with the chest freezer, which removes the biggest practical barrier. If the budget is genuinely tight, starting with chicken mince and only moving to pricier proteins once you've seen how he responds is the sensible approach.
That's really helpful. One last thing — anything I need to watch for in the first few weeks switching over?
inparticular.ai
Yes, a few things worth knowing. First, transition gradually — replace about 25% of his current food with raw on day one, increase every three to four days. Sudden switches on large dogs can cause loose stools that are hard to manage. Second, expect stools to look different: smaller, firmer, and sometimes a pale grey-white colour is completely normal on raw. Third, weigh his portions properly for the first month rather than eyeballing — 68kg is easy to slightly overfeed, and weight creep on a giant breed goes unnoticed until it's a problem. Finally, always defrost in the fridge overnight, never at room temperature, and clean his bowl thoroughly after each meal. Get those habits locked in from the start and you'll find the whole thing becomes very straightforward.
