The dog food calculator determines the number of calories and the appropriate amount of dog food based on age, weight, and activity level. This way ensures that the dog receives proper nutrition and portion size.

Understanding Your Dog’s Nutritional Needs:

Understanding the nutritional needs involves overall health including the appropriate balance of proteins, fats, carbohydrates, vitamins, and minerals tailored to the dog’s age, size, activity level, and health conditions. It is based on the research conducted by the Center for Pet Nutrition in Leicestershire, England.

Research has shown that an adult dog’s daily diet can contain up to 50% carbohydrates by weight including 2.5 – 4.5% fiber. A minimum of approximately 5.5% diet comes from fats, and 10% from proteins.

How Do Calculate How Much Food To Feed My Dog?

To calculate how much food to feed the dog you can follow the steps below;

  • Determine Your Dog’s Weight: In pounds or kilograms, weigh your dog which serves as the basis for calculating daily food intakes.
  • Assess Your Dog’s Activity Level: Look at how active your dog is. A higher activity level requires more calories.
  • Calculate Daily Caloric Intake: Use a calorie calculator and calculate caloric intake based on weight and activity level
  • Divide Calories by Food’s Caloric Density: Usually, the density of calories is listed on the package so divide the calories by their density to get a feeding amount of food.
  • Monitor Your Dog’s Weight and Adjust as Needed: Monitor the weight of the dog and adjust food accordingly


A 10kg (22lb) adult neutered dog of healthy weight needs RER = 70(10kg)3/4 ≈ 400 Calories/day.
