Goodmorning Dawn
I am so sorry to hear about your dog. Even though everyone else is telling you to get a new puppy right now, I think that would be rather difficult with you in enforced bed rest to care for a needy puppy. THere's lots of time for that.

I hope you can do exercises in bed to keep the rest of your body happy. (no, i really can't imagine)

I check for posts from you every day. One day at a time, enjoy your dog now while she's there. You have so much more time to be with her. If you were working and cycling, you wouldn't have that much time
Take care
Mimi
