This free overweight dog feeding planner tells you a gradual reduced-calorie daily plan for a dog that needs to lose weight, from current weight, target weight and food energy, with a safe weekly loss guide. It runs fully in your browser, so nothing you type is sent to a server, and you need no account and no sign-up to use it.
Many dog owners guess the daily amount, and guessing is where most feeding problems start. Too much food over months quietly adds fat, while too little food leaves a dog thin, tired, and hungry. A simple calculation based on weight and energy gives you a fair starting point instead of a guess.
To use the tool, type in Current weight (kg), Target weight (kg), Food energy (kcal per kg). Press the calculate button and the tool shows the result at once. If you change any number, press calculate again to see the new result right away.
The result is a guide for a healthy dog, not a medical order. Dogs differ in breed, age, health, and daily life, so use the number as a starting point, then watch weight and body shape over the next few weeks and adjust in small steps.
Please note: this tool is an educational estimator only and is not veterinary advice. If your dog is ill, very old, very young, or has a health condition, ask your vet before changing the diet.
Example: a 20 kg dog aiming for 16 kg, on a 3,500 kcal per kg food, would move from about 927 kcal a day to a planned 741 kcal a day, about 212 grams, losing roughly 0.17 kg a week over about 24 weeks.
Aim for slow loss. About 1 percent of body weight per month is a common safe guide for dogs. Faster loss can cost muscle and cause hunger, begging and scavenging.
Weigh weekly, at the same time of day. Daily weights jump around with water and meals, but a weekly trend shows clearly whether the plan is working.
Keep walks and play steady. Food cuts do the main work, but regular gentle movement protects muscle and mood while the weight comes down.
Common question: Is this veterinary advice? No. This is an educational estimator only. Dogs with illness, thyroid problems or joint pain need a vet plan before any weight-loss diet.
Common question: What if the weight stops falling? Plateaus are normal. Check treats, table scraps and measuring accuracy first, then ask your vet before cutting further, because too large a cut is not safe.
Common question: Should I use a light or weight-control food? It can help, because you can feed a fuller bowl for fewer calories. The total daily grams from the plan still matter more than the bag label.
Keep a simple notebook for a month. Write the daily grams, the weight each week, and any notes about energy, coat, and stools. That short record turns a vague feeling that something changed into clear evidence you can show your vet, and it makes the next adjustment much easier to judge.
A steady routine helps more than a perfect bowl. Feed at the same times, measure with scales, keep fresh water out, and give walks and play at regular hours. Dogs settle well into routines, and a settled dog is easier to weigh, easier to watch, and easier to feed well.
Finally, check the food bag for feeding guidance and compare it with this result. If the bag guide and this tool differ a lot, start between the two numbers and let the weight of your dog over two weeks decide the final amount. Write both numbers down so you can compare them again after the first weighing.
This tool is free to use as often as you like. Bookmark it, recheck the numbers when your dog grows, changes food, or changes activity, and keep the daily routine steady. Small, steady habits matter far more for a dog than any single perfect number.
