Raw dog food calculator

How the raw dog food calculator works

Raw feeding is measured as a percent of body weight rather than in calories. Most adult dogs eat about 2 to 3 percent of their ideal weight per day. The calculator multiplies your dog weight by the percent for your goal: around 2 percent to lose weight, 2.5 percent to maintain, and up to 3 percent for active dogs or to gain. It then shows the daily total in ounces, grams and pounds.

It also splits the total using the common 80/10/10 balance: 80 percent muscle meat, 10 percent raw edible bone and 10 percent organ, with liver as about half of the organ share. Those figures give a simple, balanced starting plan that you adjust by watching your dog weight and stool.

The 80/10/10 balance explained

Muscle meat is the bulk of the diet and provides protein and fat. Raw edible bone supplies calcium and firms up the stool, but too much causes hard, chalky droppings and constipation, while too little leaves them loose. Organ meat, especially liver, is rich in vitamins and is fed in small amounts because it is potent.

Heart, gizzard and green tripe are muscle meat, not organ, even though people often assume otherwise. Keep organ to secreting organs like liver, kidney and spleen, with liver at roughly half. Rotate proteins over time for a fuller range of nutrients.

Adjusting for puppies and activity

Puppies burn energy growing, so they eat a higher percent of their current weight, often around 8 percent under four months and easing to 4 to 6 percent as they mature. Because they are still growing, use the current weight for puppies rather than a target weight, and recalculate as they gain. Large and giant breed puppies need careful calcium and bone balance, so involve your vet.

For adults, use the ideal body weight you are working toward, not the current weight if your dog is over or underweight. Very active or working dogs sit at the top of the range, and you fine tune from there by feeling the ribs and checking the waist every few weeks.

How much raw food by weight

These are rough daily amounts across the 2 to 3 percent range, from a slim or senior dog at the low end to an active one at the high end. Use your dog ideal weight, and confirm with the calculator.

• 10 pounds: about 3 to 5 ounces
• 25 pounds: about 8 to 12 ounces
• 50 pounds: about 16 to 24 ounces
• 75 pounds: about 24 to 36 ounces
• 100 pounds: about 32 to 48 ounces

BARF and prey model diets

Two popular styles share the same base. Prey model raw, or PMR, feeds only meat, bone and organ, close to the 80/10/10 balance this calculator uses, aiming to mirror a whole prey animal. BARF, which stands for biologically appropriate raw food, keeps that meat, bone and organ core but adds a small share of vegetables, fruit and sometimes oils or supplements.

Both approaches work when they are balanced over time. The 80/10/10 split is a solid starting point for either one: prey model feeders keep to it, while BARF feeders trim the muscle meat slightly to make room for plant matter. Rotating proteins across weeks helps both cover a wider range of nutrients.

Transitioning your dog to raw

Switch gradually rather than overnight. Start with a single, easy protein such as chicken or turkey for several days so the stomach settles, then introduce raw bone and finally organ once things are steady. Add each new protein on its own for a few days, which makes it easy to spot any that do not agree.

Some dogs do better with a clean switch and others with a slow blend from their old food, so watch appetite and stool and go at your dog pace. Feed at fridge temperature, not frozen, and never leave raw food sitting out for long.

Reading the stool and adjusting bone

Your dog droppings are the best gauge of whether the bone level is right. Firm, formed stool means the balance is good. Hard, white and crumbly stool that is difficult to pass means too much bone, so lower the bone share and raise the muscle meat. Loose or runny stool often means too little bone, so add a little more.

Make changes in small steps over several days rather than all at once, and give the gut time to respond before adjusting again. Over a few weeks you will settle on the exact balance that suits your dog.

Handling raw food safely

Treat raw meat for your dog with the same care you would for your own food. Keep it frozen until a day or two before use, thaw it in the fridge, and use clean bowls, boards and utensils. Wash your hands and surfaces after handling, and clean up any spills promptly.

Raw feeding is not for every household. Homes with very young children, elderly people or anyone with a weakened immune system should weigh the hygiene demands carefully, and any dog with a health condition should switch only with vet guidance.
