Estimate only. Split into 2 meals a day. Puppies and pregnant dogs vary — always confirm with your vet.
How much should I feed my dog?
This estimates roughly how much food to give per day — turning calorie needs into actual cups or grams.
What the terms mean
- kcal/cup — the calorie density printed on your food bag; the tool uses it to convert calories into a portion.
- How it differs from the calorie tool — the calorie tool gives the energy target; this one turns that target into how much to scoop.
How to use it
Check your food's kcal/cup on the bag for the most accurate result, split the daily amount into two meals, and fine-tune by watching your dog's weight.
Common questions
Why does the bag's guide differ from this?
Bag guides are generous averages; this tailors to your pet's weight and goal — use the weight trend to fine-tune.
Cups or grams — which is better?
Weighing in grams is most accurate; cups are convenient but vary with scooping.
Once or twice a day?
Most adult dogs do best with two meals; puppies need more frequent ones.
How the calculation works
The calculator uses the standard veterinary energy formula. First it finds your dog's Resting Energy Requirement (RER) — the calories needed at rest — then multiplies it by an activity factor to get the daily energy need:
- RER = 70 × (body weight in kg)0.75
- Daily calories = RER × activity factor
- Food grams = daily calories ÷ food energy density
Because every dog and every food is different, treat the result as a starting point. Monitor your dog's body condition and adjust over a few weeks.
