You're welcome, Mistress! She reminded me of the few I've seen! Some people take "Deer" Chihuahuas as something rare and special and sell them for high dollar, but most just think of them as "mutts" and don't value them. They're both wrong! They are Chihuahuas, just not bred to standard. (Which I find bad.. It's like the "teacup" thing.)
My guess is she was with someone who thought she wasn't "valuable" and thought of her as a mutt and didn't care or something along those lines. It is very possible!
