I'm so sorry that she's not improving. I know that you're probably very tired of paying vet bills and not receiving the results that you would like. I feel your frustration because I've been going through a much similar situation with Starr.

I finally decided to take him to a holistic vet. Yes, she is expensive but so far it's been worth every penny. He has to be on a grain free diet which he's been on for a while but it's just not enough for him even with the pred. He's now on 3 different types of herbal supplements that I just mix in with his wet food and he loves it. I should notice an improvement in 7-10 days. The first day I gave him too much wet food so this caused him to have some diarrhea so I added some dry to it and spaced out his supplement mixture and today he's been fine. I can also tell that he's been feeling much better. I hope to be able to eventually wean him off the pred and all of the supplements too.

Here's a link if you'd be interested in finding a local holisitic vet : American Holisitic Vet Search. Here's another link that may also help: Vet Locator. I searched these by typing in the words holistic vet list. I hope that something will be able to help poor Miley. Good luck.
