They have a weight of six pounds or less and a height of five to eight inches.
Both short- and long-haired Chis are acceptable, though the latter need more maintenance to keep their coats in good condition.
The puppies are devoted to their human family but may be timid around new people.
Chihuahuas are wonderful watchdogs because, despite their little stature, they are quite protective.
In addition to being quite autonomous thinkers, they are also quite talkative.
Having a small child around increases the chance of injury to the Chihuahua (though they may bite if provoked),
therefore it's best to keep them away from homes with young children.
