Allan,
All I can say is I'm sorry. I've been there more than once and don't envy you at all. We love our children (read dogs) and cuss them from time to time but love them greatly. My wife and I refer to ourselves as Momma and Daddy when we talk to the boys. They seem to understand. They throw their love at us unconditionally, then suddenly say goodbye.
I wish you peace in your heart my friend.
God Bless,
