So our dog just died.....

I am sorry to here that your ol' friend is no longer with you but just think of those wonderful 16-17 years that you all had with him. I know the feeling that your experiencing, I've felt it three times in my lifetime. Go hang on your girlfriend or see if she'll get up and watch TV with you or just talk. Whatever you do, lean on her and others until you're ok with it. Again, my condolences and get some sleep when you're ready.
