Since there are so many colors of the Chihuahua dogs and a lot of owners wondering about all of these... let's try to sort out exactly what some of the colors actually mean:
Black Sable Fawn:
This Chi will be fawn with black sabling. Sable refers to black tipped hairs. Therefore, the base color will be fawn (light tan) and the tipping of the hairs will be black. This creates a textured appearance that is quite beautiful.
Black:
A full, solid black is very rare. Many black Chihuahua dogs will have some type of marking on the body.
Red:
This can range from a dark orange or a brown/orange and is often referred to as mahogany.
Brindle:
This is actually a pattern. It is a particular striping. Most brindle Chihuahuas are black over fawn; this will look similar to 'tiger stripes' which can be thin or thick.
Chocolate:
Chocolates have brown fur; however, there is more to it than this. A true chocolate colored Chihuahua will be so based on skin color. Instead of black eye rims, nose, lips, and paw pads, these areas of skin pigmentation will be brown.
