Dog dying. Any advice?

[Backwater Under_Duck]

Okay guys. I probably know all I need to know about this, but I have to ask you fine people before I throw in the towel.

Picked up a terrific little pooch from a local dog rescue oufit. I would find a way to post a picture, but she's so beautiful it would really break your heart. I had specifically been looking for a dog to save after outliving my my last dog-pound mutt. I had her for 19 years. I've always had cats & dogs, and I'm well-versed in the ins and outs of pet ownership/companionship.

The dog is a small-to-medium terrier cross, about 1-1/2 yrs old, all white with brown patches over each eye. Better looking than that cool dog in the Disneyland commercials. She was pulled out of a hell-hole of a dog impoundment center by the rescue lady when her time there was "up", if you know what I mean. I got her maybe a few days later. She recieved her vacinations and was spayed before she left the pound.

After a few days she's hacking a little "kennel cough". Into the vet for x-rays and antibiotics. She has developed a fierce case of tracheo-bronchitis which goes into a full pneumonia (we think), but we're getting her to eat and drink a little. After more than a week, the cough subsides and we think we're getting somewhere. Except she's listless, depressed as the doc puts it and sleeping all the time. She's not coming around.

Vet just called with results from yesterdays bloodwork. She's positive the dog has distemper. Prognosis: Zip
This vet isn't used to seeing distemper - who is anymore? She didn't exactly say we had to hurry-up and decide what to do. The dog isn't in pain or in that much distress, so she said we could continue to nurse her if we liked. Of course she's now throwing up the food they gave us to gently force feed her, so she's somewhat distressed.

Anyway, the vet made it clear that she's expecting us sooner or later to put little Dulci down. I guess I picked the wrong week to.... you know.

So what do you think, folks. Any experience saving a puppers from distemper?
Like I said, I know enough to know how bad it is.

But I had to ask.
