So pleased that we are not the only crackpots!! Teal is Tealy bobs and Willow gets called Wills, Willy Wombat and all sorts of other rude things (when she wakes up early, with the "I'm up and so should everyone else be!" attitude, not good at 6 am).
Not sure whats going on with the Boo thing, but my friend David calls his GSP Boo, her name is Bracken! Their collies are Kite aka Popsy, Ice aka Icicle, Sika aka Seeks, and Nell aka Noo Noo. Another friend refers to her red collie as Gumdrop - he's called Gus!
