I have sent her a text with an update, and asked if she's sure of the litter date, she says it's the only litter born 5th December, in the breed supplement that's sent out by the kennel club.
Ok been digging a little more, there's a puppy called fenris, born 18th Jan 2013, mother is ZAKASIA FRANKIE, can be viewed with pup from last year's litter that they kept, Ripley. If you trace the sire, it's AMBERZITA ARAZ VON THURLOW, he's listed as fathering Ripley, born 5th of December 2011, so they DID have a litter, why they would deny it I don't know.
But, I've seen pictures of AMBERZITA, he's almost jet black and very, very heavy coated.
