Feeding notes for Chihuahuas
A Chihuahua's whole day might be 200–250 kcal, and a single ounce of cheese is a fifth of that. Tiny dogs get fat on amounts that look like nothing, so weigh food in grams. Puppies are prone to hypoglycemia and need frequent small meals until about 4 months. Dental disease is near-universal in the breed; kibble sized for toy mouths helps.
Portion numbers use the same RER/MER formulas as the main calculator. Full formula sources and limits: About & methodology.

Frequently asked questions
How many cups of food should a Chihuahua eat per day?
A typical spayed/neutered adult Chihuahua (3–6 lb) needs roughly 141–237 kcal per day, which is about ½ to ¾ cups of an average 375 kcal/cup dry food, split into two meals. Use the calculator with your dog's actual weight and your food's real kcal/cup for a precise number.
How much should a Chihuahua puppy eat?
Puppies need far more per pound than adults: 3× resting energy before 4 months and 2× from 4–12 months, spread over 3–4 meals. Because the amount changes as they grow, weigh your puppy every week or two and re-run the puppy calculator with the current weight.
