She had heard about this on FB, and suggests that the pups were stolen to order, and probably moved to Ireland where it is apparently easier to smuggle them abroad, where there is high demand for working cockers. She said that if you advertise on the Internet, you have to provide your address somewhere, which can be accessed by the computer savvy thieves. She advises finding homes by personal contact only, keep the house locked and never have the dogs left in the car alone for a minute.
I hope the pups are found safe, but the heartbreak for owners is overwhelming.
