I'm so sorry for your loss, Jean. Your tribute is beautiful, and I'm glad you and Mitzi had these wonderful years together and that you enjoyed her playful, bubbly personality.
I know all too well what you are going through with continuing to catch yourself starting part of Mitzi's care routine and realizing she's gone because the same is happening with me with the routines that filled my days that are no longer needed.
For a few days I was like one of those ducks in the shooting gallery that goes one way, spins around and back the other way, rinse & repeat...like that bouncing around the house.
We've had too many losses of ODO dogs lately. It's much too much to bear.
