Kristin, I agree with you that separation is good for them. I had to leave Annie yesterday and put her in her kennel. She seemed to do really well, and was so happy to see us when we got home. Then everything changed. Her potty routine changed...she refused to go potty on her wee pad, pottied on the deck, and refused to potty before bed. Ugh....she such a stubborn little stinker.
This morning, everything seems fine. Followed her routine, and is now sleeping next to me.
