We would all love to see pictures of Coco, she sounds wonderful. My LM was very calm, he never acted like a dog due to his background. I remember a vet telling me I should train him, so that he can learn to sit, stay and other commands. At that point he was old and I liked him the day it was. Their cute quirks make them who they are so why change it! One of the hardest things after he passed was seeing all his friends walking and knowing that we could not join them. It took me about a month before I was able to venture outside with my neighbor and her dog (LM's GF) we walked the same path we would everyday and talked about his memory.
Take care and looking forward to seeing the pictures.
