Chihuahuas are the smallest dog breed but are known for their big personalities. They are energetic, confident, and love being the center of attention. Despite their tiny size, Chihuahuas believe they’re much bigger and won’t hesitate to stand their ground. They are loyal, affectionate, and protective of their owners, making them great watchdogs. However, Chihuahuas can develop Small Dog Syndrome if overindulged, becoming stubborn or aggressive. Early socialization and consistent training are crucial to ensure they grow into well-mannered pets. Chihuahuas are ideal for those seeking a small dog with a bold attitude.
