Rick,
I buried my special dog of 16 years just a few weeks ago... I know how you feel.
Carl sounds a lot like Chance...
He didn't belong to you... You belonged to him.
I miss Chance dearly, especially his loving kisses.
It's hard for me to look at his picture right now, but it does help to remember the good times and put aside the experience of his last three days.
Remember the good times and hang on to those memories.
Chance was the second dog I've belonged to in my life...
