I am sorry. I don't know what to tell you.
Love her name!
I used to have a Yorkie named, Kiwi, as a child. Best dog ever!!! Now I have one named, Strawberry!
Hehe!
My Kiwi had a pink freckle on her black nose. It started out as a tiny spec and grew with age. It never took over her whole nose. I don't think it was allergies though.
Good luck. I hope you find your answer!
