Sorry I am late to this.
Thank goodness you were there to hold your friend as he passed.
I lost Meatloaf early this year myself.
I now have Zeppelin. He will never replace Meatloaf, but he is a happy, fat sausage, that makes my happy.
This is my advice to you; Wait a few weeks and then get another one.
It will be an entirely new friendship, with the same love that you had, but different with each dog.
That is the wonderful part.
