A Chihuahua must be chosen with care, as the temperament of its owner can make a difference in the temperament of the pup. Ill tempered 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 owner 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 over other dogs, These traits generally make them unsuitable for households with children that are not patient and calm. 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 believe is their den.
