So sorry to see that things have got worse. Your poor girl. Completely understand that the money must be a worry - but just to repeat my experience: if I had gone to an expert canine dermatologist sooner than I did, I would have saved money. Because he solved the problem in three visits. I spent more with my original vet not solving the problem. Of course that's not to say that it would be the same for your girl, but it might be.
This has to be one of the saddest things I have seen. I feel so bad for you and your lovely pup. I had and have a similar issue. I say had because I am on my forth Lab, and all of them have had skin issues. After all of the trials and tribulations, what helped me was switching to them to a fish diet. You could do raw fish and greens and I am sure she would respond very nicely. What ever you decide to do, best of luck and wishes to you and your family, especially your pup!
