Calculate your dog's daily nutrition needs easily with our free Dog Nutrition Calculator. Accurate, fast, and ideal for all breeds, weights, and ages.
Feeding your dog the right amount of food is one of the most important parts of keeping them healthy, happy, and energetic. But figuring out exactly how many calories and nutrients your dog needs can be confusing. Every dog is different based on weight, breed, age, and activity level. That’s why we created our free Dog Nutrition Calculator a simple tool that helps you calculate your dog's exact daily calorie needs along with the perfect balance of protein, fats, and carbohydrates. Whether you are feeding kibble, making homemade dog food, or planning a diet for your puppy, our calculator gives you accurate answers fast and easy.
Our calculator is built on veterinary-approved formulas like Resting Energy Requirement (RER) and Maintenance Energy Requirement (MER). These formulas are widely used by vets and pet nutritionists around the world to determine how many calories a dog should eat daily.
The formula for Resting Energy Requirement (RER) is simple:
RER = 70 × (Body Weight in kg)^0.75
Once the RER is calculated, we find the Maintenance Energy Requirement (MER) by multiplying the RER by an activity factor based on your dog's age, health, and activity level:
MER = RER × Activity Factor
For example, a neutered adult dog will have a lower activity factor (1.2), while a very active working dog will have a higher factor (3.0).
After calculating the total calorie needs, we also break it down into suggested daily amounts of protein, fat, and carbohydrates based on healthy nutritional guidelines.
Using our Dog Nutrition Calculator is very simple and quick. First, enter your dog’s current weight. You can select whether you want to input the weight in kilograms or pounds. Next, choose your dog's activity level from the dropdown menu. Then click on the "Calculate" button.
Our tool will instantly display:
You can use these results to plan your dog's meals whether you are buying pet food or making homemade dog food.
If you are wondering "how do you calculate homemade dog food?", it's now easy. With our calculator, you know exactly how many grams of each nutrient to include daily based on your dog's personalized needs.
Many pet owners guess how much food their dog needs, but guessing can lead to serious problems. Overfeeding can cause obesity, diabetes, and joint problems. Underfeeding can cause weakness, poor coat health, and even organ issues.
By using a dog calorie calculator by weight and breed, you can give your pet the right number of calories, keeping them at their ideal weight and promoting a long, healthy life. It also helps you maintain a safe calorie deficit for dogs if your pet needs to lose weight, without risking their health.
Puppies, in particular, have very different needs compared to adult dogs. That's why we also included a puppy calorie calculator setting that adjusts the nutrition needs for growing puppies.
Our Dog Nutrition Calculator is the best and easiest way to find out how much food your dog needs every day. Whether you are feeding a small puppy, an energetic Labrador, or an older senior dog, our tool gives accurate results you can trust.
You can also use this calculator to figure out the best homemade dog food nutrition, and you’ll never have to wonder again, "how many calories should a 13 lb dog eat?" or "how do I calculate my dog's ideal weight?"
Remember, a healthy diet means a longer and happier life for your dog. Start using our free Dog Nutrition Calculator today and make sure your furry friend gets the perfect amount of food every day!
To calculate homemade dog food, you first need to know your dog's daily calorie needs using RER and MER formulas. Then divide those calories into the right percentages: around 30% protein, 20% fat, and 50% carbohydrates. Our Dog Nutrition Calculator makes this process super easy.
A 13 lb dog (about 5.9 kg) typically needs around 250 to 400 kcal per day, depending on their activity level. You can use our calculator to get the exact number.
Your veterinarian can help determine your dog's ideal weight by examining their body condition. However, as a rough guide, if your dog looks overweight or underweight, you can aim to adjust their diet by about 10% fewer or more calories and monitor their health. Our calculator can help you plan a safe calorie adjustment.
A safe calorie deficit for dogs is usually around 10-20% fewer calories than their normal Maintenance Energy Requirement (MER). It's important to make gradual changes and monitor your dog's weight and health with your vet's guidance.
