Okay, so we went to the vet today. We had an ice storm and the vet had a lot of cancellations, so I was able to get a same day appointment.
I saw a different vet than I saw the last time. Today it was a woman who also happens to be the owner of a German Shepard who has similar issues as our girl.
The fact that she cleared up the last time with steroids tells her it is probably an allergy. That said, she took some skin scrapings to look for mange. She was able to tell me in minutes that it was not mange. But the dog does have a skin infection that is secondary to the allergies and the direct result of all the scratching.
Now, if it is allergies, we have a long and maybe painful road to follow. Dogs can be allergic to damned near anything ...... including cats and other dogs! Determining the actual allergy is as hit and miss, as painful, and as expensive for dogs as for humans. So most vets wind up treating them symptomatically. And that's what we're going to do for Big ... for now. The vet said that antihistamines can be very effective and have no know side affects, even if taken every day for life. They don't help with where Big is now, but they are proven to be efficacious as a preventative. Further, there are a number of them available, each working a slightly different way.
So .... right now it is another course of steroids. That will give her pretty fast relief. Then, just before the end of the steroid course, we will start the antihistamine. She said these are effective about 50% of the time. So we start with this one ... evaluate ..... and move to the next and the next if need be.
Plan B is to do the serious allergy testing or put her on steroids for ever. That's where it starts to get really hard.
Here's a link to pictures of the rest of Big's family, all of whom are pulling for her.

She was bought as a puppy direct from an amateur breeder. She is full GSD, but not of any particularly good bloodline. Just your basic German Shepard. The couple that got her were friends with my son since childhood. The wife died of cancer and the husband had a drug problem and was ultimately unable to cope; he's no longer functional. My son and DIL took in the dog, as it was either that or she would have wound up who-knows-where .... maybe euthanized. So they kept her as long as they could, but knew they would be moving and likely not able to keep her. They found a great home for her, but the woman who was to take her couldn't do so for a month or so (whatever ... not sure I trusted the story from the start). "Dad, can you watch her until she can pick her up."
So we take her. Of course, we've known this dog basically since she's been a puppy. The bonding part was unavoidable. We told my son to tell whoever he found to take the dog that the dog is no longer available.
Yeah .... we're saps.
But who couldn't love her? She's just so damned sweet.
