Chihuahua Food Calculator: How Much to Feed a Chihuahua
Quick answer: An average adult Chihuahua (4 lb / 1.8 kg) needs about 175 kcal a day if spayed or neutered — roughly 0.46 cups of a typical dry food, split into two meals. Chihuahua puppies need more per pound: about 0.39 cups a day at 2 months, rising to 0.54 cups by 6 months.
A starting point, not a prescription. Weigh your dog every 2-4 weeks and adjust by about 10% if they gain or lose weight you didn't intend. Treats should stay under 10% of daily calories.
