All 11 pups went upstairs for overnight. They appeared to be playing well together all yesterday. So, everyone felt that a transition was not necessary. I watched them almost all night. The mothers slept. I watched. What a crazy person I am. Moms all have been through this before so they know the drill. They were excited to see them in the morning.
It went really well. Tonight they will be heading upstairs again without moms.
The pups are growing up!
