Chihuahua is a lively, charming, and intelligent breed. They are very devoted to their owners, though usually only choose one or two “favorites”. Not only do they give affection, they in turn demand it. Their creative and curious nature drives them to create various ways to gain your attention. Owners of more independent breeds may find the Chihuahua too needy. Households with older children are preferred, as they can be injured easily by younger children. Valued for their loyalty and courageousness, they often become “full of themselves” and will challenge much larger dogs and strangers, and because of their size this can often result in severe injuries or possibly death. They are also very suspicious of strangers (which also makes them good watchdogs), and will not let you out of their sight. It’s often said they have “terrier-like” qualities… as they are very alert, observant, bold and saucy.
They are very clannish nature, meaning that they’d choose to be with other Chihuahuas, over other dogs. Some can be quite the sun-bathers, choosing to lay in the sun for hours, thought this must be closely monitored to avoid heat strokes. Their gentleness and sweet nature makes them perfect for elderly and handicapped people. Never leaving your side, they will lay in bed with you for hours on end; preferably under the covers… of which they love.
They can sometimes be overly insecure and high-strung, which can result in separation anxiety. Chihuahus are known to bark excessively when left alone for too long. If you find yourself out of the home for long periods of time, then this is not the breed for you, as they thrive on their humans. They are also not recommended for being in a home with small children (unless raised with them) as they may resort to biting in self defense. Many tend to be fairly dog-aggressive. Their level of devotion to their humans can become a problem, as they are sometimes overly jealous of their humans relationships with one another and animals.
