I don't
know you, but I know you from your posts over the last few years and I don't for one second think you are projecting hopes. Of course you have hopes, but you're a realist and you're just giving her every chance you can with all the love and respect you have for her.
Having been in a similar situation with a dog her age I know the battle you have and to be honest, whilst I didn't like what happened to my boy, if I had to do it again with one of my current dogs at that age, I'd probably make the same choices and keep trying until a vet I respected told me otherwise - or my dog told me clearly. She'll let you know if she doesn't want anymore and she may never give up - Trev didn't, but until then, keep working as a team and keep trying..

It's totally exhausting and worrying about decisions and what you're doing is a massive factor in that, but try not to question yourself, just trust your gut feeling and Tills to guide you
She's a Strong, dignified, beautiful girl and couldn't be with anyone better, you know that, so I hope that helps a little at the moment - she's had a really cracking time with you to date and is getting everything possible to help her now, what a gift

.
I wish more than anything I could change things for you both and I'm still hoping very hard for a bit of stabilisation and a little improvement.
