Fresh dog food typically delivers 40 to 60 calories per ounce, versus 100 to 130 for dry kibble, because roughly 70 percent of it is water. On a dry matter basis, most gently cooked recipes land around 30 to 45 percent protein, 20 to 35 percent fat, and whatever remains in carbohydrate. Those percentages are not comparable to kibble percentages until you strip the water out of both.
Why can't you compare a fresh label to a kibble label directly?
Because guaranteed analysis is printed "as fed," water included, and the two foods contain wildly different amounts of water. A fresh recipe listing 11 percent crude protein looks anemic beside a kibble listing 26 percent. Convert both to dry matter and the fresh food is the richer of the two, often by a wide margin.
This is the single most common misreading in pet nutrition, and it isn't the shopper's fault. Labels are legally required to report as-fed values. Nobody is required to explain that comparing them across moisture levels produces nonsense.
How do you convert guaranteed analysis to dry matter?
Divide each nutrient percentage by the food's dry matter percentage, then multiply by 100. Three steps:
- Find moisture on the label. Say it reads 72 percent.
- Subtract from 100 to get dry matter: 100 - 72 = 28 percent.
- Divide each nutrient by 0.28. Crude protein of 11 percent becomes 11 ÷ 0.28 = 39 percent on a dry matter basis.
Run the same arithmetic on a kibble with 10 percent moisture and 26 percent protein: 26 ÷ 0.90 = 29 percent. The fresh recipe is meaningfully higher in protein, which was invisible in the as-fed numbers.
How many calories does your dog actually need?
Start with resting energy requirement, then multiply by an activity factor. RER equals 70 times body weight in kilograms raised to the 0.75 power. For a 20 kg dog: 20^0.75 is about 9.5, times 70 gives roughly 665 calories at complete rest.
Multiply that by 1.6 for a neutered adult dog with normal activity and you get about 1,065 calories per day. Intact adults sit near 1.8. Dogs on a weight-loss plan often run at 1.0 or slightly below RER under supervision. Highly active working dogs can climb past 3.0.
These multipliers are population averages, and individual dogs vary by 20 percent in either direction from metabolic differences alone. The formula gives you a starting point, not a prescription. Weigh your dog every two weeks and let the scale correct the number.
How much protein is enough?
AAFCO sets the floor at 18 percent dry matter for adult maintenance and 22.5 percent for growth and reproduction. Most fresh recipes clear both by a comfortable distance, which is generally a good thing: dietary protein supplies the amino acids that maintain lean muscle, and lean mass is a large part of what determines resting metabolic rate.
Higher isn't infinitely better. Dogs with certain kidney or liver conditions need protein managed rather than maximized, and that management is a veterinary decision, not a shopping decision. For a healthy adult, though, a 35 to 45 percent dry matter protein level is a reasonable and useful range. Our piece on reading a guaranteed analysis panel walks through where these numbers appear on a package.
How much fat is too much?
Fat carries 9 calories per gram against 4 for protein and carbohydrate, so it drives calorie density more than any other factor. A recipe at 30 percent dry matter fat can pack 25 percent more calories per ounce than one at 20 percent, with no visible difference in the bowl.
AAFCO's adult minimum is 5.5 percent dry matter, mostly to ensure adequate essential fatty acids. Practical ranges run much higher. What matters is matching fat level to the dog in front of you: an active adolescent Lab burning through a winter of hiking uses that density well. A ten-year-old Corgi with two naps a day does not, and the same recipe becomes a weight problem within a season.
Do dogs need carbohydrates?
Dogs have no established dietary requirement for carbohydrate — they can synthesize the glucose they need from protein and fat. That's a real physiological fact, and it's also frequently overstated. "Not required" doesn't mean "harmful." Carbohydrates from sweet potato, oats, or vegetables supply fermentable fiber that feeds gut bacteria, add volume that helps a dieting dog feel fed, and cost less per calorie than meat.
The useful question is proportion, not presence. Kibble usually needs 30 to 50 percent carbohydrate on a dry matter basis just to hold its shape through extrusion. Fresh recipes have no such structural constraint, which is why Turkey Reduced Carb can push carbohydrate down and protein up in a way a dry food physically cannot.
How do these numbers change for weight management?
For a dog who needs to lose weight, the lever is total calories, and the protein percentage is what protects muscle while those calories come down. A common approach is feeding to the RER for the dog's target weight rather than current weight, then reassessing monthly. For a dog who should weigh 18 kg but currently weighs 23 kg, that means roughly 610 calories a day instead of 1,150.
Safe loss runs about 1 to 2 percent of body weight per week. Faster than that risks lean tissue loss and, in some dogs, other complications.
Do not run this plan alone. Ask your veterinarian to set the target weight and the calorie figure before you cut anything, because an obvious "my dog is overweight" can turn out to be a thyroid issue, a medication side effect, or arthritis that limits movement — and a diet aimed at the wrong cause wastes months.
How do you translate all this into a scoop?
Use grams, not cups, and let the calorie figure drive the number. If a recipe runs 48 calories per ounce and your dog needs 1,065 calories a day, that's 22 ounces, or about 625 grams, split across two meals.
A kitchen scale removes the guesswork that scoops introduce; volume measures of a moist, compressible food vary by 15 to 20 percent depending on packing. Then verify against reality: weigh your dog every two weeks and run a hands-on body condition check using the WSAVA body condition scoring chart. Ribs should be easy to feel under light pressure with a visible waist from above. If the numbers say one thing and your hands say another, trust your hands and adjust by about 10 percent.
Frequently asked questions
Why does fresh dog food have fewer calories per ounce than kibble?
Water. Fresh food is around 70 percent moisture and kibble around 10 percent, so an ounce of fresh food contains far less dry nutrient material. That's why fresh portions look enormous next to kibble portions at the same calorie count — you're feeding a larger volume of a less concentrated food.
What is a good protein percentage for a fresh dog food?
On a dry matter basis, 35 to 45 percent suits most healthy adult dogs, well above AAFCO's 18 percent adult minimum. Read the as-fed number on the panel and convert before judging it. A recipe showing 11 percent as fed at 72 percent moisture is delivering roughly 39 percent dry matter protein.
How do I calculate my dog's daily calories at home?
Convert weight to kilograms, raise it to the 0.75 power, multiply by 70 for resting energy requirement, then multiply by 1.6 for a typical neutered adult. A 30-pound dog is 13.6 kg, giving an RER near 495 and a daily target around 790 calories. Adjust based on two-week weight trends.
Are low-carb dog foods better?
Better for some dogs, unnecessary for most. Lower carbohydrate typically means higher protein per calorie, which helps dogs managing weight or holding muscle as they age. Healthy, active dogs generally do fine across a wide carbohydrate range. Match the formula to the dog rather than to a category label.
Should I count treats in my dog's daily calories?
Yes, and cap them at 10 percent of the daily total. For a dog eating 1,000 calories, that's 100 calories of treats — which two large biscuits and a few training rewards will use up quickly. Treat calories are the most common reason a carefully calculated meal portion still produces weight gain.
