Chihuahuas are tiny toy dogs with big personalities and a strong tendency to bond closely with one or two favorite people. They can be confident and bold, often acting like a much larger dog in a small body. Because of their size, gentle handling and early socialization are important to prevent fearfulness or snapping. Chihuahuas do well with short walks and indoor play, and many enjoy training games and tricks. Warmth and dental care are key parts of Chihuahua health.
Chihuahuas are associated with Mexico and are believed to descend from small companion dogs kept by ancient civilizations. They became widely popular as portable companions and show dogs.
