I feel your pain, as a short while ago a similar thing happened to my black lab. Right now it probably feels as though nothing will ever make the pain you are feeling and that hole in your heart go away. But you will heal with time and you will be able to cherish those wonderful memories of Rebel. Roxy is feeling a great loss too, so give her a big hug and shed those painful tears with her. God Bless you, I am so sorry for the loss of your angel Rebel.
