What are the characteristics of chihuahuas?


assistant
Chihuahuas are among the smallest of the dog breeds. Small in size but confident and big-dog natured. They originated from Mexico with lineage going back to ancient kingdoms of pre-Columbian times. Chihuahuas are extremely loyal, known for having close attachments with their owners. Their distinct features include oversized, pointy ears and expressive eyes. Coats come in many colors ranging from white to brown to black with many different pattern variations, and will be either short or long. Short hair chihuahuas are known for shivering and needing sweaters in cold weather. They are ideal city dogs given their small size.
