Here is a peek into the wonderful mystery of nature using today's technology.  These are Ultrasound images of the puppies at 4 weeks of development.  5 more weeks to go.  Isn't this wonderful!?  From this stage the puppies develop a bit more, then they grow and grow until time for delivery. We were able to see heartbeats in these views.  Currently we are past week 5 and as you can see from my previous post, Ginna's tummy is now starting to show that she is pregnant.  She doesn't act differently yet and is still as agile and active as ever. 

  The canine uterus has two horns and fetuses place themselves along those horns on either side of her body.  I am not sure about how the puppies organize themselves for delivery, but it certainly is a miracle of birth.
