Chihuahua Full Grown: Size & Weight
A full-grown Chihuahua weighs about 2–6 lb and stands roughly 5–8 in tall at the shoulder.
Some breeders advertise a "teacup" Chihuahua, but there's no official teacup standard: it's just the small end of the breed's normal range, roughly 2 to 4 lb.

About this breed's data: Weight is AKC official standard verbatim: not to exceed 6 lb (over 6 lb is a disqualification). The AKC standard states NO height; the ~5-8 in figure is a common breed-info reference, NOT from the standard. 'Teacup' is not an AKC category.
