The Chihuahua weight chart is a good guide to estimate the weight of a fully grown chihuahua. Please note it is only a guide, as many things can affect the weight of a mature puppy. This can dependend on genetics, bloodlines, feeding and excercise.
Weight estimates before 8 weeks are usually inaccurate as the puppy will usually still be nursing or being weaned and may well be heavier due to fat from the mother's milk.
The weight chart becomes more accurate when the puppy gets older.
The weight chart is from "The Complete Chihuahua Encylopedia" by Hilary Harmar published in 1972.
