Dog Food Calculator: Daily Feeding and Water Guide
Use this calculator to estimate your dog’s daily food amount, calories, meal split, and water needs. It includes breed search, food type choices, custom calories from your food label, and simple safety notes.
Before You Use the Calculator
This tool gives a general estimate using common RER/DER energy formulas. It is helpful for planning, comparing food labels, and building a feeding routine, but it does not replace veterinary advice.
Use your dog’s current weight, choose the closest breed, and edit the kcal per 100g if your food label gives a different number.

Important Safety Note
This calculator is for general educational use only. Dogs with medical conditions, pregnancy, nursing, unusual weight loss or gain, digestive problems, allergies, kidney disease, diabetes, pancreatitis history, or growth concerns need veterinarian-guided feeding plans.
Always keep fresh water available and compare this result with the feeding guide on your dog food package.
How to Use This Feeding Result
- Start with the estimate, then watch body condition, stool quality, appetite, and energy.
- Make food changes slowly unless your veterinarian tells you otherwise.
- For puppies, choose a food made for the correct growth stage and size.
- For large and giant breed puppies, ask your veterinarian about safe growth and mineral balance.
- For senior dogs, monitor appetite, water intake, teeth, mobility, and weight changes carefully.

Dog Food Calculator FAQ
Is this calculator a replacement for my veterinarian?
No. It is a general planning tool. Your veterinarian should guide feeding for medical conditions, growth concerns, weight problems, pregnancy, nursing, or special diets.
Should I use current weight or ideal weight?
For a normal-weight dog, use current weight. If your dog is overweight or underweight, ask your veterinarian whether to calculate from current weight, target weight, or a special feeding plan.
Why does wet food show more grams than dry food?
Wet food usually has fewer calories per 100g because it contains much more moisture. That means the gram amount can look higher than dry kibble.
Can I add my own dog food?
Yes. Choose the custom food option and enter the kcal per 100g from the food label. You can also enter grams per cup if you use cups at home.
How often should I feed my dog?
Many adult dogs do well with two meals per day. Puppies may need three or four meals. Senior dogs may benefit from smaller, easier meals. Ask your veterinarian for your dog’s needs.
Does the water number include wet food moisture?
The water number is a general drinking-water guide. Wet food adds moisture, but fresh drinking water should still be available at all times.
What if the food bag says a different amount?
Use this result as a comparison. Food labels vary by recipe and calorie density. Ask your veterinarian which target is better for your dog.
