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.

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%.

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.

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%).

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.
