I agree - I would definitely get an x-ray. This way you know how many puppies to expect, a more exact day of delivery, as well as if they are all facing the right direction. She does look very large for 44 days, Even with Rosie's 2nd litter she didn't appear that large by day 44. I definitely don't miss waiting for Rosie to have her babies, but I sure miss the babies after they get here!
