The word "Chihuahuas" refers to a breed of dog that is tiny in size and often known for their quirks. However, if you need to find other words to describe these little canines, you could try "toy dogs," "pocket pets," or "teacup dogs." Alternatively, "Mexican dogs" may be a useful synonym for highlighting their origin while "apple-head dogs" could refer to their distinctively round skulls. Additionally, labels such as "yappy dogs" or "lap dogs" might accurately convey their traits and temperament. Regardless of the term selected, Chihuahuas are beloved for their spunky personalities and adorable appearance.
