I'm so sorry to hear your distressing news about the OS. Glad you've joined the CoG. They were a God-send to me when I lost my Derby girl last year. Good pain mngt. is critical, as well as knowing when it's time to say goodbye. All three of mine had the fast-growing type of OS, and only made it 6 weeks from the first limp to failure of the leg with horrible swelling that couldn't resolve. Your precious girl lives in the NOW. Give her whatever she loves to eat, take lots of pictures, love on her, and cherish every moment. My prayers are with you both.
