Frequently Asked Questions
How do veterinarians calculate a dog's daily calories?
Veterinarians use the scientific WSAVA formula. First calculate Resting Energy Requirement: RER = 70 × (Weight in kg)^0.75. Then multiply RER by a life-stage factor (1.6 for neutered adult, 1.8 for intact, 1.2 for weight reduction, 2.0 to 3.0 for growing puppies) to find Maintenance Energy Requirement (MER).
Why are dog food bag feeding guides often too high?
Pet food manufacturers publish broad average feeding charts that often lead to overfeeding and canine obesity. Over 50% of dogs in the US are overweight; calculating exact calories according to WSAVA formulas and adjusting based on body condition score prevents weight gain.
How many cups of food are in a standard 30 lb bag of dog food?
A standard 30-pound bag of dry kibble contains approximately 115 to 125 measuring cups of food (averaging about 4 ounces or 110-120 grams per cup).
Should treats be included in the daily calorie total?
Yes! Treats, dental chews, and table scraps should never make up more than 10% of your dog's total daily caloric allowance, with the remaining 90% coming from complete and balanced AAFCO-approved dog food.
