I think it's so nice that they are so close to you. Toto will probably find he loves having friends to play with!
It's nice that you got to spend some time with them. However things turn out with Shira, I'm certain that she will be loved for the rest of her life. I could be wrong, but I would think that a little dog that had been treated the way she was treated would be a bit stand-offish with people until she grew to trust them. I think her hair is pretty. Kacee's head is turning pale blonde and her back is turning silver.
