How Many Calories a Day Is Right for a Dog?

Dogs require a certain amount of calories based on energy levels, breed and size in order to maintain a healthy life. Most commercial dog food lists its nutritional information, as well as suggested feeding guidelines, on the packaging. The packaging should also be labeled with the number of calories per cup or per can.

  1. Significance

    • Dog owners need to know the weight, breed and energy level of their pets to make sure they are not over or under feeding them.

    Considerations

    • An underweight dog can suffer from weak muscle tone, slower healing and decreased energy. An overweight dog can suffer from arthritis, diabetes, decreased energy and even skin problems.

    Formula

    • Nutritionists use a Resting Energy Requirements (RER) formula for calculating caloric needs of dogs. The RER is the basic amount of energy a dog would use in a day while remaining at rest. The formula is based on weights of 5 to 99 pounds. The formula used is: RER in kcal/day = 30(body weight in kilograms) + 70.

    Prevention/Solution

    • Not all dogs require the same amount of calories. An owner cannot base the amount needed on age and weight alone. Breed, size of dog and energy level are among the factors that influence the specific calories a dog requires.

    Simple Guideline

    • A general guide to feeding your dog: Feed according to the product label found on the dog food package. The owner can then adjust the amount fed to his dog based on the dog's weight gain. If the dog is becoming over weight, decrease the amount fed. If your dog is not gaining well and is very active, increase the amount given per package directions.
