My Chelsey does the mirror checks all day long, people wont believe me till they see it for themselves! She acts completly normal till she's dressed with a bow in her hair, thats when she changes into a different creature, i know its nuts, but she cant even act "normal" to her yorkie friends when they visit us unless she's nekked and in a mess... (they are not allowed to touch her) This behaviour is now even starting to rub off on little Chanel, tho she can still be polite and friendly to her friends.
Chelsey is a compleet snob except towards her little sister Chanel (they play pretty us together)
