The Chihuahua is the smallest dog in the world, and one of the most popular pets. Despite its small size, it is fearless, daring and protective toward its owner and its territory. It is also cautious toward strangers, and is always on guard, traits that make it a good alert-dog. It cannot coexist with energetic small children, and it rarely coexists peacefully with other pets. It has the tendency to bark a lot, but with the proper training this tendency can be curbed significantly. It may live in an apartment, as long as it gets its daily exercise. It enjoys human company and likes being petted.
