I'm so sorry.  Over the years, we have lost several beloved dogs, and can understand completely the depth and scope of your loss.  It seems there's no purer love than that between human and canine; and no purer sense of grief when the inevitable loss occurs.  I know there are dogs in heaven.... at least I'm counting on it...  May your grief soon turn to beautiful memories, and the thought of your sweet friend bring nothing but joy.  mcw1917
