I'm so very sorry to hear your news. OS is a particularly nasty cancer to fight, and since it's already metastisized to her lungs, there's not much that can help. Spoil her rotten... feed whatever she loves, spend as much time with her as possible, take lots of pictures, manage the pain with effective doses of meds, and cherish every minute you have with her. Be strong in her presence, and cry when she can't see or hear you. These puppers are so very sensitive, and you don't want to worry her any more than necessary. Pebbles lives in the present only, and doesn't see what's ahead. Keeping you both in my prayers for comfortable days ahead and much more quality time with your baby girl.
