Since reading about Molly my firend has had a similar experience.
She already has a dalmation and at long last OH has agreed that they have another. They found a breeder who was due a litter and registered an interest in a puppy from that litter. They arrived just before Easter except all 11 puppies have popped out as black retrievers (with a couple of white spots under chin).
It seems that she must have "got out" just before mating to the pedigree Dalmation.
HOWEVER, I can't understand the fact that the breeder was advertising puppies at £300 and my research for her since this unfolded as made me think the breeder was anticipating they might not be pure breed because this seems very cheap. I am positive that if they'd been spotty, they would have been sold as dalmations when in fact they probably were not, I wonder if the mating with the dalmation was hastily arranged to cover the KC registration, not sure if dog and bitch were hers.
Anyway friend has decided not to buy but her friend is although not sure what they now intend to sell at!
Glad your mystery is unfolding and I bet she'll be a pretty girl regardless of her breeding. You could try small claims court to get money if needed, the threat might be enough and if they don't pay you could ask baillifs to intervene - depends how far you want to take it.
