How a Chihuahua behaves Chihuahua temperament depends on the genetic temperament of their parents and grandparents. Their small size makes them delicate and vulnerable to injuries and attacks from larger animals. Like all dogs, they benefit from appropriate socialization and training. Chihuahuas tend to learn better when being rewarded positive reinforcement, such as a treat or praise. With the proper training a Chihuahua needs, this dog can be extremely intelligent. The way a dog is trained will influence its behavior.
Chihuahuas are fragile and can be easily frightened, so are generally unsuitable for homes with small children. The breed tends to be fiercely loyal to one particular person and in some cases may become overprotective of the person, especially around other people or animals, 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.
Because Chihuahuas get cold easily they tend to 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. Chihuahuas sometimes act like cats and climb up to the highest point on a couch, usually on top of the pillows, and curl up into a ball. Chihuahuas have their own type of personality. They tend to be alert. Chihuahuas typically do not show fear; even though they are a smaller breed, they do not view their size as a disadvantage.
