My munchkins have a couple of collective nicknames - they both come a running if I call "York-ee-toes", And I call them "Yorks of Yorkington" and the "terrorists" tho they don't respond to those.
Dixie is also called:
Evil Wee
Weeevil
Liddle
Precious
Lil Stinker
Licky Puppy
Dougal is
Dooooogs
Dougalicious Dougalvator
Dougal the Dugong
Little Man
And sadly my husband's trained him to answer to Stupid

, and a couple of other names which I can't put on this site!
I love everyone's nicknames they're so cute!
