I was wondering if anyone could tell me, Do you always feel alot of movement out of the pups the last few weeks before they're born or are some litters kinda quite? Our girl has had 2 litters previously, and they all been pretty rowdy, but this litter is different they barely move at all. I can only feel little flutters every now and then. I was thinking that maybe it was because we seen 6 sacks on the x-ray and maybe they just don't have a whole lotta room to be dancing around. Any thoughts????
