i wanted to add. this is like me have anywhere from 2-8 babies inside my belly all weighing about 10lbs each as a human example. That dog is 5lbs and those pups could be a 1/2 to a 1lb each. If there are 5 pups that's more than the mother weighs.
think about trying to pass 5 ten lb babies through your birth canal...not happenin
btw this is a very exaggerated example*** |
