The Chihuahua is known by its small size, big ears, large, dark eyes and its eccentric personality. Some have even joked that the Chihuahua is not really a dog but a descended of rats. Although small in body and size, it is a strong, robust breed. The body is longer in length than its height, and the coat can either be long or short depending on the variety. Colors include brown, fawn, chestnut, and black and tan.

A nested case control (NCC) study is a variation of a case-control study in which only a subset of controls from the cohort are compared to the incident cases. In a case-cohort study, all incident cases in the cohort are compared to a random subset of participants who do not develop the disease of interest.
