Tonight I was finally able to let Lucie run around the living room.
My husband and I had to move in with my parents for awhile, and when we got here their house was a disaster, so I had to spend some time cleaning so it was safe for the puppy to run around.
I put her in the living room and she found Duke, starting biting at him, he ran away, and she started chasing him and he finally started playing with her!
I'm so relieved they are starting to get along.
I tried getting some pics, I'll have to look at them all tomorrow to see if they turned out alright.
