What is 80/10/10 raw dog food?

80/10/10 is the ratio most UK raw feeding is built on: 80 percent muscle meat, 10 percent edible bone and 10 percent offal, with the offal split into 5 percent liver and 5 percent other organs. Here is what each part does, what the ratio misses, and the grams for your dog.

80/10/5/5 muscle, bone, liver, other organ

The short answer

Take your dog's daily amount, 2 to 3 percent of body weight for an adult, and divide it: 80 percent muscle meat, 10 percent bone, 5 percent liver, 5 percent other secreting organ. For a 20 kg dog on 500 g that is 400 g of meat, 50 g of bone, 25 g of liver and 25 g of kidney or spleen. Rotate the meats, add oily fish weekly, and you have a diet that is close to balanced. The calculator produces these four lines for any weight.

What each part does

Share	What it is	What it supplies	Too much looks like	Too little looks like
80% muscle meat	Mince, chunks, heart, tripe, tongue, gizzards, fish, eggs	Protein, fat, B vitamins, iron, zinc, taurine	Soft dark stools (usually because bone is short)	Rarely a problem in practice
10% edible bone	Chicken wings, necks, carcasses, turkey necks, lamb ribs	Calcium, phosphorus, magnesium, trace minerals	White, chalky, hard stools, straining	Soft stools, and over months, bone weakness, especially in puppies
5% liver	Any animal's liver, rotated	Vitamin A, copper, folate, B12, vitamin D	Loose stools within a day. Long term, vitamin A excess	Dull coat, poor skin, over time vitamin A and copper shortfall
5% other organ	Kidney, spleen, pancreas, brain, testicle, thymus	Selenium, B vitamins, iron, vitamin D (kidney)	Loose stools	Narrower nutrient range, especially selenium

Why liver is split out

Liver is the most nutrient dense food in the diet and the easiest to overdo. It is extremely high in vitamin A, which is stored in the body rather than excreted, so a diet with 10 percent liver every day for years risks vitamin A excess. It is also rich enough that a sudden 50 g of liver gives most dogs loose stools. Holding liver at 5 percent and filling the other 5 percent with kidney or spleen keeps vitamin A in range and widens the mineral intake. It is the one place where the ratio is precise on purpose.

Worked examples by dog weight

Figures for an adult dog on 2.5 percent of body weight. The last column converts the bone target into chicken wings, which are 45 percent bone. Change the daily percentage for activity and age with the feeding guide.

Dog	Daily	Muscle (80%)	Bone (10%)	Liver (5%)	Other organ (5%)	Bone as wings
5 kg	125 g	100 g	13 g	6 g	6 g	28 g
10 kg	250 g	200 g	25 g	13 g	13 g	56 g
20 kg	500 g	400 g	50 g	25 g	25 g	111 g
30 kg	750 g	600 g	75 g	38 g	38 g	167 g
40 kg	1000 g	800 g	100 g	50 g	50 g	222 g

Note the wings column: because a wing is meat as well as bone, the dog eats about 110 g of wings to get 50 g of bone, and the 60 g of meat on them comes out of the muscle meat allowance. The bones guide has the bone share of other options.

What 80/10/10 does not cover

The ratio is a good approximation of a prey animal, but farmed meat is not a prey animal. Three gaps show up repeatedly when home prepared raw rations are analysed.

Omega 3 fats. Grain fed beef, pork and chicken are low in EPA and DHA. Oily fish once or twice a week, or a fish oil, fills it. The fish guide has amounts.
Iodine. There is almost none in muscle meat, bone or organ unless you feed thyroid, which you should not. A pinch of kelp is the usual answer in DIY diets.
Vitamin E, zinc, manganese. Often low in meat only diets. Variety helps (red meat for zinc, mussels for manganese), and some feeders add a modest vitamin E dose, particularly when feeding fish oil.

A German analysis of 95 home prepared raw rations found most fell outside recommended ranges for at least one nutrient, with calcium and vitamin D the most common. The ratio gets you close; variety and a few additions get you the rest. Or buy a complete, where the manufacturer has done it.

80/10/10 done for you

Durham Animal Feeds completes are 80 percent meat, 10 percent bone, 10 percent offal by the brand's own description. Nutriment builds on meat, bone, heart, liver and kidney. Natures Menu's 80/20 range is the BARF style alternative.

Questions

Frequently asked questions

Is 80/10/10 the same as 80/10/5/5?

Yes. 80/10/10 is the short form. The last 10 is offal, and it is always meant to be split into 5 percent liver and 5 percent other secreting organs. People who write 80/10/5/5 are spelling out that split, which matters because feeding all 10 percent as liver is too much vitamin A and feeding none is too little. The calculator on this site shows the four lines for that reason.

What counts as "other organ" in 80/10/10?

Secreting organs: kidney, spleen, pancreas, brain, testicles, thymus (sweetbread) and, in small amounts, lung. Heart, tongue, gizzard, tripe and trachea are muscle in this system even though a butcher calls them offal, and they go in the 80 percent. Kidney and spleen are the easy ones to buy in the UK.

Is 80/10/10 a complete diet?

Not by itself, and this is the honest answer the ratio's fans sometimes skip. 80/10/10 gets the big things right: protein, fat, calcium and phosphorus in the right ranges, and vitamin A and copper from the liver. Analyses of home prepared raw rations have found shortfalls in iodine, vitamin E, vitamin D, zinc and manganese in a large share of them. Variety of proteins, oily fish weekly, and sometimes a kelp or vitamin E supplement are how DIY feeders cover those. Commercial "80/10/10 complete" products add what is missing to meet FEDIAF guidelines.

Is 80/10/10 the same as BARF?

No. 80/10/10 is prey model raw: all animal. BARF (70/10/5/5/10) takes 10 percent off the muscle meat and replaces it with vegetables, fruit and sometimes seeds or dairy. Both are used widely and both produce healthy dogs when the rest is done right. The BARF vs PMR guide compares them in detail.

Which UK raw brands are 80/10/10?

Durham Animal Feeds describes its completes as 80 percent meat, 10 percent bone, 10 percent offal. Nutriment's core recipes are built on muscle meat, bone, heart, liver and kidney with added extras. Natures Menu's 80/20 range and Bella + Duke are 80 percent meat with 20 percent fruit and vegetables, which is a BARF style split rather than 80/10/10. The brand comparison has the detail and prices.

Do I feed 80/10/10 every meal or over the week?

Over the week is fine for adult dogs and is how most people do it: a bone heavy meal, then boneless meals, with liver two or three times a week. The totals should land near 80/10/5/5 by Sunday. Puppies do better with bone in every day because their calcium intake should be steady. Dogs with sensitive stomachs do better with liver spread thinly across meals rather than a large liver day.
