My dog was named Sandy too, we literally put her down 4 days ago. She was a lab/german shepherd mix and would have been 14 years old in August, it absolutely killed me especially since she was in perfect health aside from her legs and hips. She got hip dysplasia a few years ago and was still mobile until a year ago where it worsened but was she was still ok and got around. Then suddenly in the past 2 weeks it got a lot worse, and in the 3 days before she died it got so bad, and she couldn't even get up anymore on the last day. It all happened so fast and the house has felt dead and empty for the past 4 days now
