She's beautiful. And she always will be.
Dogs tend to age much more gracefully than we humans. For one thing, they don't feel sorry for themselves. They just keep living every day.
We had a Golden who lived to be 15, Harvey Garvie. Harvey was pretty feeble during those last couple of years but whenever he'd lose his rear and fall, he'd just bounce back up as if to say "don't worry, dad, I'm fine. They need to repair that sidewalk." He never lost either his dignity nor his love of living. May it be true for us, too.
