Here are Oshi and Sasha in February 2007 when they were 3 months old. That black and tan scoundrel turned into the white and tan Oshi scoundrel. Such colour change is normal apparently. Jet black Sasha is now greying. Her black has faded. 🐶

Oshi at 3 months, with largely black and tan face.Sasha at 3 months, with shiny jet black hair.
