Well, maybe she's a mutt bunny! Coloring can change, but most of her is still all white, by the time Miss Hoppy was "half grown" her coloring had already changed.

Dwarves (Netherland Dwarf bunnies, Dwarf Hotots - which have dark around the eyes, not the nose) are 2-3 pounds, so even if her ears didn't indicate otherwise, you know she's not either of those!
