I know sadly what you are going throuh, as All of Our Companions are only here on Earth for such a short time.
You had Peanut a long time, and took her travelling so she got to see different places and enjoy herself.
Now she with her Tubby Friend and Tubby 2 , and she is able to travel so many places now, and show the other Angels where she has been.
And you will travel together in Paradise again.
One Fine Day.
