The Chihuahua is a good companion dog. Courageous, extremely lively, proud and enterprising, it gives and demands affection. Bold and saucy, it moves swiftly to avoid being stepped on. Chihuahua's are strong-willed, intensely loyal and become very attached to their owners, even to the point of jealousy. They like to lick their owner's faces. It is undeniably suspicious of people except for its owner. When strangers are present, it follows its owner's every move, keeping as close as possible. For some, they may be slightly difficult to train, but they are intelligent, learn quickly, and respond well to proper, gentle training.
