Her coloring gets darker and smoker looking as you move from her golden face to her tail.
Her name doesn't need to reflect her coloration but it wouldn't hurt either. She almost has a heart on her side, but it isn't anywhere near as noticiable as her sisters. My sister has already suggested "Smokey Bottom" - not happening Tia!
UPDATE: Well that didn't take long! A Facebook fan suggested "Nutmeg" and my husband added "Waltz" so she is now known as "Wags Ranch TC Nutmeg Waltz".
