That dog was something else.
As is your tribute to her. Well said, and an emptiness only filled by another in time, never quite the same, but uniquely present.
I have been blessed with five dogs in my lifetime who had tremendous personalities and were anchors for the family, companions, and are still sorely missed. My current one, "Peaches", is a rescue and she, too has stepped into that role. It's hard when they go, because of the hole it leaves in everyone's lives, one which you describe well.
