For a singleton Flatcoat puppy, black & a bitch. No Solo's please! Something original, pup's mum is Shambles and owner's other FCR is Kaos so something a little bit different please!
Well as Shambles means untidy/messy (originally a Shambles was an abbatoir!) Kaos means, well chaos..... So you can think along the lines of messy as in "whatamess", disruption, naughtiness, stormy, whirlwind, tornado, hurricane, trouble.... sure that will inspire something, look up these words in a Thesaurus perhaps?
Shambles used to be the old term for butchers shops, my grandparents used to own a silversmiths shop in the Shambles in York, which is a famous tourist attraction. So I'm thinking maybe something like Sylvan, similar to silver, but meaning of the woods......
what about havoc, mayhem or trouble? My staffy is Missy as in misdemeanour which would tie in with kaos and co. If you are going with the butcher theme what about marjery or lovett taken from Sweeney Todd - perhaps a bit too different!
I've suggested Havoc but it was thought, too masculine! Like Shambles & Kaos are feminine! Mayhem would be shortened to May which they didn't like either.
