I feel your pain!
Except I have a 7 year old Maltese who has decided she isn't house trained anymore.
Basically, she pees on the floor before I wake up in the morning.
I cage her during the day, for 12 hours (yes, I know, horrible... but it's the best I can do with my work schedule)... so I hate to cage her at night too. That, and she will bark the entire time.
My solution? Diapers. Yep. She wears diapers at night. And for some odd reason, she doesn't realize that she is peeing on herself every morning. It's annoying... and I have to spend 30 minutes every morning cleanin her up and washing the diaper.
After the new year, I'm going to look into options to find her a new home. I love her to death, but obviously I can't train her and my lifestyle doesn't work for her.
Otherwise... your dogs are SO CUTE!!!!
