What a pretty sweet little girl you have! I dont know if this will be helpful to you but I'll post it. When I got my puppy LilGirl two years ago, I put her in a cage at night & she cried alllll night & I felt terrible. No, she did not poop in cage. She's always been good about going out when I take her plus she was mostly trained when I got her.

Anyway the second night when I put her in cage she cried & cried & I let her out & she came to my bedroom where I was... found some of my dirty clothes on the floor next to my bed & she made her bed there. She was so sweet. I then took her little round bed from the cage and put it on top of my dirty clothes & she was satisfied... and she has been sleeping in that spot ever since (not on the same clothes though LOL). She was just so lonely but being near me, even on the floor, was ok with her.

Heidi really is a cute little dog & I enjoy looking at your photos.
