Enter your dog weight in kilograms. This dog food portion calculator uses a planning rule of 20 grams of dry food per kilogram of body weight per day, which sits inside the common 2 percent to 3 percent of body weight range used by competitor feeding guides. It converts the daily grams into cups at 120 grams per cup, and splits the day into two meals in the guidance below. These figures are estimates for planning, not professional veterinary advice.
The dog feeding chart by weight theme runs through every competitor guide: adult dogs commonly start near 2 percent to 3 percent of body weight per day in food. This calculator uses 20 grams per kilogram, which is 2 percent, as its planning rule. A 20 kg dog therefore starts at 400 grams per day, and a 10 kg dog starts at 200 grams per day, before activity and body condition adjustments.
Dog food grams per day are the reliable number, since cups vary by kibble size and density. This calculator converts at 120 grams per cup, so 400 grams reads as 3.3 cups. Dog food calories per cup also vary, typically 300 to 450 kcal for standard kibble, so always check your bag: a calorie dense food needs fewer cups for the same daily energy.
Puppy dog food amount runs higher relative to body weight, since puppies grow fast and often need several small meals a day. Adult dog food per day is the maintenance case this calculator models. Senior dog food amount usually falls slightly, since older dogs move less, but senior dogs still need protein rich, digestible food, so do not cut portions on age alone.
Active dog food amount rises with exercise: a working or agility dog can need substantially more than a couch companion of the same weight. Raw dog food percentage body weight guides use 2 percent to 3 percent for adults and higher percentages for puppies, which matches this calculator rule in grams. Judge the result by body condition, not appetite: you should feel ribs easily without seeing them, and adjust by 10 percent at a time.
Dog feeding twice a day is the standard adult pattern: split the daily total into two equal meals, morning and evening. Dog food per meal for a 20 kg dog is therefore 200 grams, or about 1.7 cups, per meal. Puppies need 3 to 4 meals a day, and any food change should be gradual over a week to avoid stomach upset.
How much to feed a 20 kg dog on this rule: daily grams are 20 times 20, which is 400 grams, and daily cups are 400 divided by 120, which is 3.3 cups. Split into two meals, that is 200 grams per meal. A 10 kg dog starts at 200 grams per day, or 1.7 cups, which is 100 grams per meal across two meals.
A common starting point is about 2 percent to 3 percent of body weight per day in food, adjusted for activity and food type. A 20 kg adult dog starts near 400 grams per day on this calculator rule.
Puppies need more food relative to body weight than adults, split across 3 to 4 meals a day. Use the puppy guidance on your food bag and your vet advice, since growth stage changes the amount fast.
About 3.3 cups at 120 grams per cup. Cups vary by kibble, so weigh food in grams when you want an accurate daily amount.
Twice a day suits most adult dogs: split the daily total into two equal meals. Puppies need more frequent meals, and senior dogs usually stay on two meals unless a vet advises otherwise.
Yes. Kibble is calorie dense, so it needs fewer grams and cups than wet food for the same energy. Raw feeding is usually planned as a percentage of body weight, near 2 percent to 3 percent for adults.
Not on appetite alone. Most dogs act hungry even when fed enough. Check body condition and weight trend over 2 to 4 weeks, and adjust by about 10 percent if weight moves the wrong way.
No. These figures are estimates for planning, not professional veterinary advice. For puppies, senior dogs, overweight dogs or dogs with health conditions, ask your vet for a personal feeding plan.
