The Chihuahua has such a unique temperament, which is a definite benefit of owning this breed of dog. This breed prefers to attach to one or two people and is incredibly loyal to its owner.
Almost all Chihuahuas need lots of human contact. If your dog feels as though it is not getting the required amount of petting, touching, and loving, it will let you know by doing something to get your attention, such as lightly pawing your leg or hand, whining, or rolling on its back at your feet.
If you plan to have more than one Chihuahua, you may find your dog becomes less stressed when left alone. For example, if you work and will be out of your home for long periods, two Chihuahuas might be better than one. They will most likely try to keep each other company.
With their kind temperament, watchdog-like qualities, low exercise requirements and devotion - this breed of dog is excellent for disabled, elderly, or single people. The Chihuahua will literally lie in your lap for hours, being perfectly content.
Chihuahuas also love to curl up and sleep under covers. For this reason, you should expect that the foot of your bed, under the covers, would be occupied by your dog (which is great for keeping your feet warm on a cold winter night).
