Willow is the only one from a puppy, I was going to call her Buffy but Mr CS said no and as Mr CS only suggested 7of9 (star trek thing), she became Willow - or more often called Toad as she is a wee Toad.
Bilbo, was called Sam, didnt like it, and he had big hobbity feet.
Paddy, came from Ireland and was called Peal so something beginning with P, again Mr CS wouldnt let me call him most of my suggestions but his full name which does get used often is Patrick O'Gara O'Driscoll Kennedy
Dobbie - umm, he was called Oscar, not at all an Oscar

, he was going to get a sensible working name like Ghillie, but spent his life carrying socks about and just wiggled when Mr CS called him Dobbie - he really really suits it and he is the only Dobbie I know
