My parents had a chi years ago that looked about the same color and they said she was a fawn color. This has been probably 30 years ago, do they still have a color fawn for chihuahuas? I call Sassy cream, she is very light color but not white. Maybe I am all off on the colors. I don't know, my parents chi was AKC but Sassy isn't.
Anyway, you have 2 very cute, sweet looking babies.
