Thanks very much for your prompt reply. I bought her from a breeder. The breeder is in as much shock as me. I do know that she has mated with either an airedale or a labrador as she had both breeds. I also have the date of her last season.

I am trying to locate a sheep scanner but I've been told by one farmer that it is very expensive to call out for one dog. But I will keep trying. I just feel this information would be very helpful in terms of dates and how many pups to expect so I know they are all born.

Also where on earth do you buy whelping boxes from? They don't stock them at my local pet shop!
