CanlıDostumDog & cat calorie calculator
Enter your pet's weight and life stage to see daily calorie needs, how much food that is in grams and ounces, and a sensible treat limit.
- Uses the RER formula from veterinary nutrition
- Neutered, intact, puppy/kitten, senior and weight-loss factors
- Works in kg or lb
How the calorie calculation works
The calculator uses the two-step method common in veterinary nutrition: resting energy requirement (RER), then a life-stage factor.
1. Resting energy requirement (RER)
2. Daily needs = RER × factor
| Life stage | Dog | Cat |
|---|---|---|
| Neutered adult | × 1.6 | × 1.2 |
| Intact adult | × 1.8 | × 1.4 |
| Puppy / kitten | × 2.0 – 3.0 | × 2.5 |
| Weight loss (ideal weight) | × 1.0 | × 0.8 |
| Senior / less active | × 1.4 | × 1.1 |
| Active / working | × 2.0 and up | — |
3. From calories to grams
These values are a starting point. Two pets of the same weight can differ by up to 20%. The best guide is the weight trend over 2–4 weeks.
Frequently asked questions
How many calories does a 10 kg (22 lb) dog need?
For a neutered adult dog, RER is about 394 kcal; × 1.6 gives about 630 kcal a day. An intact dog needs about 710 kcal.
How many calories does a 4 kg (9 lb) cat need?
For a neutered adult cat, RER is about 198 kcal; × 1.2 gives about 238 kcal a day.
How many grams of food should I feed my dog?
Divide daily calories by the food's kcal/kg and multiply by 1000. For 630 kcal and a 3,600 kcal/kg food, that is about 175 g (6.2 oz) a day.
Do treats count?
Yes. Treats should be no more than 10% of daily calories; reduce the main meal on days you give more treats.
How accurate is this?
The formula is a general estimate used in veterinary nutrition. Real needs vary; adjust based on weight trend and check with your vet.
