I'm so sorry your girl might have this dreadful disease!
My old girl who we lost last week had AF.
We too were first told she did not have AF but in the end the vets had to admit this is what she had.
Hers started when she was 4 and she lived a happy life until she was nearly 10(which is a good age for my breed)
We tried everything, Aloe, loads of different creams, (3 different vets), homeopathic medicine... nobody really knew what would work!
In the end I researched and researched and then told the vet what medication we want to try!!!
This is when (after about 2 years of different treatments, some working for a little while, some useless) she went on sandimmum neoral (later Atopica Vet) and that cleared the problem.
We were at the point of trying this and if it did not work we would have had to let her go and put her to sleep.
I wish we had known and started this medicine straight when the problems started, before her bum area(possible insides too) was scarred as this obviously made the caring of it more difficult with deep scarring etc!
She still had odd time the holes would start to return (seasons) but bringing the dose up for a while cleared these.
It is pretty expensive especially when the treatment starts but the amount does get cut down and the up keep dose can be pretty low after a while(depending of the dog).
