I'm so sorry for the bad news. I never give up hope until it's truly time, but I agree with everyone else who has posted, that she will have better last days at home. I've been in a similar situation with a very sick old Boston Terrier, and it was horribly sad for us, but I was glad she was with us at home until it was time for her to go to the bridge. I spent the last weekend of her life downstairs with her, sleeping on the couch, so I could comfort her between seizures, even when she couldn't see or hear me. I am very glad I had that time, even though it was emotionally wrenching, and my eyes were never dry. Our pets are just so much more comfortable at home with their "pack".
Thinking of you and Maggie Bear....
