A family friend is having a litter. I think the Dam is a BC cross. Im not sure what the sire is. They are so excited about the litter, and whont consider a spay. They arent 100% sure she is prego. But her tummy is gettting huge. I told them how to make a whelping box and to keep her inside alot. But I fear that the litter will be born outside in the barn or some other place as the dam is a outside farm dog. Any advice I can give them? I hope to be there when she whelps at least. No idea when she is due either.
