The Chihuahua dog breed‘s charms include their small size, big personality, and variety in coat types and colors. They’re all dog, fully capable of competing in dog sports such as agility and obedience, and are among the top ten watchdogs recommended by experts. Fun loving and busy, Chihuahuas like nothing better than to be close to their people. They follow them everywhere in the house and ride along in tote bags when their people run errands or go shopping. It’s not unusual for Chihuahuas to form a close bond with a single person, and they can become very demanding if they’re overindulged.
