Richard, That is a beautiful response.  I see that you also have lost your little man, I'm so sorry for your loss.  I like your way of looking at it and know what you say is true.  We could take all the guilt and blame in the world on ourselves and it wouldn't change anything except make us feel bad, paralyzed in our grief.  Yet they know we loved them, we'd have done anything for them, and often did.  I cook for my dog, for medical reasons, and he is a gentle giant so it's a lot of cooking
