Same here, by the time the Pups are 12 weeks, my Chanel is looking forward to lay in my bed and have time to herself..LOL , the runt of this last litter stayed here with me until last week and she played with her a bit more but once she went home and I took down the puppy pen,Chanel did not change at all, then again, I have 3 other dogs that keep her busy, and play with her, so I guess that helps too.. If your baby is left alone, then she might be feeling lonely , so a bit more attention will not hurt.
