Chihuahuas come in a variety of colors, with fawn being the most common. However, there are some rarer colors like pure white, jet black, lavender, and brindle. White Chihuahuas can be distinguished by their lighter eyes and delicate noses. Jet black Chihuahuas are less commonly seen as solid black without any other color markings. Lavender Chihuahuas have a diluted chocolate color, while brindle Chihuahuas have striped or streaked fur. These unique colors add to the charm of these tiny dogs.
