The pups are old enough to sleep with out their mommy. They are completely weaned and self sufficient. But with Ginny being the awesome mom that she is, will often times opt to spend the night in the pen with her babies opposed to being brought upstairs to sleep with us. Recently it has been on colder nights, providing extra body heat, but tonight it is on the warm side. Not sure why she has elected to stay with them but I can tell you that she has put them in their place!
I had to chuckle when I peeked in to see she was sprawled out comfortably in the lushly cushioned dog crate, looking out at her pups snoozing below her on the crate pad. They clearly were not uncomfortable in anyways – Simply letting the queen remain in her thrown.
