n.
Smallest recognized dog breed, named for the Mexican state where it was first noted in the mid-19th century.
It probably derived from the Techichi, a small, mute dog kept by the Toltec people as long ago as the 9th century. Typically a feisty-looking, alert dog that is sturdier than its small build would suggest, it stands about 5 in. (13 cm) high and weighs 16 lb (0.52.7 kg). It has a rounded head, large, erect ears, prominent eyes, and a compact body. The coat varies in colour and may be either smooth and glossy or long and soft.
