Tanya,
So sorry for your loss. It's always so hard. Non-pet people don't understand what our pets mean to us, so it's not a big deal to them, but all of us here know what a big deal it is, and we're here for you. Be sure to hug your mini Schnauz a little more and let him comfort you as well as comforting him. It certainly appears that he's feeling sad for the loss as well. I think the doggie daycare is a good idea. I would think that giving him as much love and attention as you can during these difficult times will help both you and him cope. Let us know how you are doing. You are in my thoughts...

Here's a little quote that I found that seems related to this topic:

"The final cause of dogs having such short lives...is in compassion to the human race; for if we suffer so much in losing a dog after an acquaintance of ten or twelve years, what would it be if they were to live double that time?"
-Sir Walter Scott
