I Built a Raw Feeding Calculator for Your Dog — Free, and Nothing Leaves Your Browser

Here’s a funny thing about writing a blog for sixteen years: you find out exactly which post people actually came for. For me it’s not a dog photo or a storm update — it’s my old raw dog food recipes post. And the question that lands in my inbox more than any other is the same three little words, over and over: how much do I feed?

So I finally built the thing I probably should have built years ago. It’s a Raw Feeding Calculator — you tell it about your dog, it does the raw-feeder arithmetic for you, and it tells you exactly how much to put in the bowl. It’s free, there’s no account and no app to install, and — the part I’m a little proud of — nothing you type ever leaves your browser. The whole thing runs right there on your screen.

The idea is dead simple. Punch in your dog’s weight, roughly how old and active they are, and whether you’re trying to keep them right where they are, trim them down a bit, or put a little weight on. Hit go and you get the daily amount in grams (and ounces, because who has a gram scale memorized), already broken into the classic 80/10/10 split — muscle meat, raw bone, and organ, with liver and the other organs counted separately the way they’re supposed to be.

A few things I made a point of building in, mostly because they’re exactly the parts people tell me they get wrong:

• Two diet models. Feeding prey-model 80/10/10? It’s right there. Feeding BARF with veggies, seeds and a little fruit? Flip the toggle and the whole recipe rebalances itself.
• Batch math. Tell it you’re prepping a week — or a whole month — at a time and it scales every number up, so you know how many actual pounds of each thing to buy.
• A shopping view. The split in “walk-up-to-the-meat-counter” weights, plus a copyable list so you’re not doing fraction math in the store.
• A cost reality check. Roughly what your homemade bowl costs per day versus buying it pre-made — handy if you’ve ever wondered whether all that chopping is actually saving you money. (Usually, yes.)
• It remembers your dog. Come back tomorrow and your last setup is still sitting there waiting.

If you’re brand new to all this, don’t sweat it — here’s the thirty-second version of what those numbers even mean.

New to Raw Feeding? The 80/10/10 in Plain English

The whole prey-model approach is really just trying to recreate, roughly, what a dog would eat if it caught dinner the old-fashioned way. Spread over a week it works out to about:

• 80% muscle meat — the bulk of the bowl. The regular cuts: chicken, beef, turkey, pork. (Heart and gizzards count here, by the way, not as organ.)
• 10% raw bone — for calcium and a bit of structure. Usually meaty bones like chicken backs or necks. Raw, never cooked.
• 5% liver — basically the multivitamin of the dog world. A small amount with a big nutritional punch.
• 5% other organ — kidney, spleen, that sort of thing. (Confusingly, this part does not mean more liver.)

Feed BARF instead and you shave the meat down a touch to make room for around 10% vegetables, plus a little seed and fruit. The calculator handles that swap for you — you don’t have to recompute a thing.

One honest note: this is a starting point, not a prescription. Every dog is a little different, and the best gauge is the dog standing in front of you — if they’re going soft in the middle, dial it back; if ribs are showing, feed a bit more. Puppies, pregnant dogs, and dogs with health conditions have their own needs, so loop in your vet on those. I get into all of that, and how I actually feed my own crew, over in the raw dog food recipes post.

That’s the whole thing. Go feed a good dog. And if you spot something that would make the calculator better, I’d genuinely love to hear it — leave a comment or drop me a line through the contact form.
