How Much Cooked Food to Feed Your Dog
Home-cooked dog food portion sizes: grams of cooked meals per day by body weight, calorie-density estimates and a batch-portioning method that scales up.
How Much Homemade Dog Food Should You Feed?
Grams per day equal the daily kcal target divided by the recipe's kcal per gram. Cooked recipes run about 1.0-1.5 kcal per gram, against 3.5-4.5 kcal per gram for kibble, so homemade portions are 2 to 3 times larger by weight than kibble portions for the same dog. Worked example: a 40 lb (18.2 kg) neutered dog needs about 999 kcal per day; on a 1.25 kcal-per-gram recipe that is 999 / 1.25 = about 800 g, or 1.75 lb of cooked food.
A rough starting rule is 2-3% of body weight in cooked food daily, which for the 40 lb dog is 360-545 g; the calorie math above lands higher because this recipe is lean. That gap is exactly why the percentage rule is only a starting check: verify it with calories every time. Get your dog's kcal target from the daily calorie target calculator first, then portion any recipe against that number.
Expect the volume shock in the other direction too. Owners switching from cooked food back to kibble routinely overfeed, because the correct kibble portion looks tiny beside the cooked portion it replaces. The bowl is not the unit; the kilocalorie is.
How to Calculate Calories in a Homemade Recipe
Recipe calorie density equals total ingredient kcal divided by cooked batch weight. USDA FoodData Central provides the ingredient calorie values; sum them, weigh the finished batch and divide.
Worked example: 1 lb of lean ground beef carries about 1,100 kcal, 2 cups of cooked rice about 410 kcal and 1 cup of mixed vegetables about 50 kcal. Total: about 1,560 kcal. If the cooked batch weighs 1,200 g, the density is 1,560 / 1,200 = 1.3 kcal per gram. The 40 lb dog from above eats 999 / 1.3 = about 770 g of this batch per day.
Weigh the batch after cooking, not before. Cooking water loss increases kcal per gram, so a batch that simmers down 20% is 20% more calorie-dense than the raw weights suggest. The same label-independent method is laid out in calorie calculation methods for pet food.
- Step 1: sum ingredient kcal from USDA FoodData Central
- Step 2: weigh the cooked batch in grams
- Step 3: kcal per gram = total kcal / cooked batch weight
- Step 4: daily grams = your dog's kcal target / kcal per gram
Homemade Portions by Dog Weight (Table)
The table assumes a neutered adult and a 1.25 kcal-per-gram recipe, with cups at about 230 g of moist cooked food per cup. An 80 lb dog eats about 1.3 kg of cooked food daily, which surprises most owners switching from 4 cups of kibble.
If your recipe's density differs, rescale the grams column: grams = table kcal / your kcal per gram. The kcal column follows the same portion fundamentals used for every food type.
| Dog weight | Daily kcal (neutered adult) | Cooked food per day (1.25 kcal/g) | Approx. cups (~230 g/cup) |
|---|---|---|---|
| 10 lb | ~346 kcal | ~275 g | ~1.2 cups |
| 30 lb | ~793 kcal | ~635 g | ~2.75 cups |
| 50 lb | ~1,167 kcal | ~930 g | ~4 cups |
| 80 lb | ~1,658 kcal | ~1,325 g | ~5.75 cups |
How Much Cooked Meat, Rice and Add-Ins
Balanced cooked diets target roughly 40-50% lean protein, 25-50% cooked carbohydrate and 10-25% vegetables by volume, plus a vet-formulated vitamin and mineral premix. The densities to plan with: cooked chicken breast contains about 1.65 kcal per gram and cooked white rice about 1.3 kcal per gram, so a 30 lb dog's 793 kcal fits in roughly 250 g chicken, 280 g rice and 100 g vegetables.
A meat-only diet lacks calcium and essential micronutrients; meat is calcium-poor and phosphorus-rich, and the imbalance shows up in bones and blood work within months. This is the reason balanced homemade diets include a vitamin-mineral supplement rather than relying on ingredient variety. Chicken and rice alone is a short-term bland diet, not a maintenance plan. The complete nutrient picture, protein, fat, calcium, and the micronutrient list, is covered in what a balanced canine diet requires.
Fat content moves the math more than any other ingredient choice. Swapping lean (93/7) ground beef for regular (80/20) lifts the example batch from about 1.3 to roughly 1.6 kcal per gram, a 23% jump that shrinks the correct daily portion by the same fraction. Recalculate the density whenever the protein source or its fat percentage changes.
Batch Prep, Storage and Portion Control
Weigh single-day portions into containers on cooking day; batch portions weighed into single-day containers remove every future measuring error. Refrigerate 3-4 days of food and freeze the rest for up to 2-3 months. Label each container with the gram weight and the batch date.
Homemade batches vary in calorie density from batch to batch, since meat fat content, simmer time and rice absorption all move the kcal per gram. Recheck your dog's weight every 2 weeks for the first 2 months after switching and adjust grams 10% at a time. Commercial foods print their density on the label, explained in how commercial labels state calories; your kitchen is the label now.
Long-term homemade diets require veterinary nutritionist balancing: a board-certified nutritionist (ACVIM or ACVN) or a formulation service verifies the recipe covers all essential nutrients. Cat households run the same math with different targets, covered in homemade portions for cats. Start every batch from a current number: run the dog feeding calculator to fix your dog's kcal target, then portion the recipe from there.
Size batches from the daily gram figure. A 30 lb dog at about 635 g per day eats roughly 4.5 kg per week, so a weekly cook of 4.5-5 kg fills seven containers with one session. Thaw frozen containers in the refrigerator overnight, never on the counter, and serve at room temperature.
Frequently asked questions
- How much homemade food should I feed my dog?
- Daily grams equal your dog's kcal target divided by the recipe's kcal per gram; cooked recipes run 1.0-1.5 kcal/g. A 40 lb neutered dog at about 999 kcal needs roughly 800 g of a 1.25 kcal/g recipe. Use 2-3% of body weight as a starting check, then verify with calories.
- How much cooked chicken should I feed my dog daily?
- Only as part of a balanced recipe with carbohydrate, vegetables and a mineral premix. Cooked chicken breast carries about 1.65 kcal per gram, so a 30 lb dog's 793 kcal day fits about 250 g of chicken inside a complete recipe. Chicken alone lacks calcium and is not a maintenance diet.
- Is homemade dog food cheaper than kibble?
- Usually not. Ingredient costs typically run 2 to 4 times kibble cost for large dogs, because an 80 lb dog eats about 1.3 kg of cooked food daily. Costs drop with bulk buying and batch cooking but rarely reach kibble prices.
