I did a search to learn about you and Shadow since you haven't posted very much. Only a few posts but I learned a lot about you
How wonderful you are that you took in an older dog when you both needed to feel love.
How great life can be again when you have someone to love.
And how amazing fate can be that you brought Rocco into your life just a few weeks ago?
I know you are sad and my heart breaks for you. Hang on to the good that you and Shadow had. And allow yourself the healing that Rocco has to offer.
Big hug.
