They looked so fantastic! I laughed at them playing and butt sniffing. I think you can start letting them out more. Ending it today on a good note was super but you can always have a second daily visit or just extend things. The only thing I would not yet do is leave them out together while I was gone all day. That will come after you have total confidence in their behavior. Bravo to them but even more applause to you..Job well done!
