RER = 70 × 20^0.75 = 70 × 9.458 = 662. Neutered adult dog multiplier = 1.6. Activity level 3 and body condition 3 have no additional modifiers. Daily calories = 662 × 1.6 = 1,059, rounded to nearest 10 = 1,060 kcal. Dry food = 1,060 / 380 kcal per cup = 2.8 cups across 2 meals.

RER = 70 × 5^0.75 = 70 × 3.344 = 234. Cat adult neutered multiplier = 1.2. Activity level 2 applies a 0.9 modifier: 1.2 × 0.9 = 1.08. Daily calories = 234 × 1.08 = 253, rounded to nearest 10 = 250 kcal. Dry food = 250 / 350 = 0.7 cups. Treat limit = 250 × 10% = 25 kcal.

Frequently Asked Questions

Q

How many calories does my dog need per day?

Dog calorie needs are calculated using Resting Energy Requirement (RER): 70 × (weight in kg)^0.75, then multiplied by activity factors. A typical 20kg adult dog needs 700-900 calories daily, varying by activity level and whether they're neutered.

  • Small dogs (5 kg / 11 lbs): ~300–400 kcal/day for a neutered adult
  • Medium dogs (20 kg / 44 lbs): ~700–900 kcal/day depending on activity
  • Large dogs (40 kg / 88 lbs): ~1,200–1,600 kcal/day for moderate activity
  • Working or highly active dogs may need 1.5–2× the standard adult amount
  • Puppies under 4 months need about 3× the adult RER multiplier for growth

Q

How do I know if I'm feeding my pet the right amount?

Monitor your pet's body condition: You should be able to feel ribs with light pressure but not see them. There should be a visible waist from above. Weigh your pet monthly and adjust portions if weight changes more than 5%.

  • Run your hands along the ribcage — ribs should feel like knuckles on the back of your hand
  • View from above: a visible waist tuck behind the ribs indicates healthy weight
  • Side view: the belly should tuck up from the chest, not hang level or droop
  • Weigh monthly on the same scale at the same time; adjust food by 10% if trending up or down
  • Treats should not exceed 10% of total daily calories — a large Milk-Bone is ~115 kcal
Q

How many times a day should I feed my pet?

Adult dogs and cats: 2 meals per day. Puppies and kittens (under 6 months): 3-4 meals. Senior pets: 2 smaller meals. Avoid free-feeding (leaving food out all day) as it promotes overeating.

  • Puppies 8–12 weeks: 4 meals/day; 3–6 months: 3 meals/day; 6+ months: 2 meals/day
  • Kittens under 6 months: 3–4 small meals; adult cats: 2 meals or measured portions
  • Feed at consistent times each day — dogs thrive on routine schedules
  • Remove uneaten food after 15–20 minutes to prevent spoilage and overeating
Q

What is the body condition score?

Body Condition Score (BCS) is a 1-5 or 1-9 scale to assess pet weight. Score 3/5 is ideal: ribs easily felt, visible waist. Below 3: underweight (increase food). Above 3: overweight (reduce food 10-20%).

  • BCS 1/5: emaciated — ribs, spine, hip bones clearly visible; urgent vet visit needed
  • BCS 2/5: underweight — ribs easily felt with minimal fat; increase food 15–20%
  • BCS 3/5: ideal — ribs palpable, visible waist, belly tucks up from the side
  • BCS 4/5: overweight — ribs hard to feel under fat layer; reduce food 10–15%
  • BCS 5/5: obese — no waist visible, large belly; vet-supervised weight loss recommended
Q

Do neutered pets need less food?

Yes, neutering/spaying reduces metabolic rate by 20-30%. Neutered pets typically need 20-30% fewer calories than intact animals. Adjust portions after the procedure to prevent weight gain.

  • Reduce food by 20–30% within 2 weeks of the spay/neuter procedure
  • A neutered 20 kg dog needs ~700 kcal vs. ~900 kcal for an intact dog of the same size
  • Neutered cats are especially prone to weight gain — 56% of US cats are overweight
  • Switch to a "neutered/indoor" formula food with fewer calories per cup if available
