Breed standards for this dog do not generally specify a height; only a weight and a description of their overall proportions. Generally, the height ranges between 15 and 23 cm (6 and 9 in).
Chihuahuas can be easily provoked to attack, and are therefore generally unsuitable for homes with small children.The breed tends to be fiercely loyal to one particular person and in some cases may become over protective of the person, especially around other people or animals. They do not always get along with other breeds,and tend to have a “clannish” nature, often preferring the companionship of other Chihuahuas or Chihuahua mixes over other dogs.These traits generally make them unsuitable for households with children who are not patient and calm. If properly managed by older children, 13 and up, they can adapt to this kind of living with a dedicated owner. The temperament of its owner can make a difference in the temperament of the pup.
Chihuahuas love their dens and will often burrow themselves in pillows, clothes hampers, and blankets. They are often found under the covers or at the bottom of the bed, deep in the dark and safety of what they perceive as their den. Chihuahuas also enjoy time in sunlight.
Taco Bell used a chihuahua as its advertising figure and mascot from 1997 to 2000.
