The picture was of a room (appeared to an foofed outdoor room - e.g. coal bunker or bin store - no plaster on walls - brickwork painted white) that appeared to be about 4ft wide (can't tell length as photo may not have been taken from the door, but assuming it was, the room was probably about 10ft long).

The photo showed the female and the pups lying at the far end with another dog (presumably the father) lying a few feet nearer the camera

The photo was grainy, but the floor was a mottled lightish brown colour. Its possible that it was brown vet bed, but it looked like it was just ground (like a plaster colour, though you wouldn't normally plaster a floor).

As for the health testing - what they say is that they have good scores 'in the family' - to me that doesn't necessarily mean the ma & pa of the pups.
