Emmy Lou. Just because she is adorable and I don't have much else to say.
On second thought I will tell you a story. Emmy Lou isn't very bright. One day she walked head first into a low brick garden wall and busted open her brow. When the skin healed and the fur grew back, it was white instead of black, see the spot? The other bits of stray white mixed into her black spot is her version of "greying", the sweet thing.
