We have progress!!! After much trial and error, Bailey had a hunch that Maze's body could be producing too much "fire" so we had to cool her down. She gave me 2 new pills to try (don't ask me the name, I don't read chinese. Lol) and stop all the rest for 2 weeks. Well Maze has been on them for a little over a week now and what a change! The fur at the base of her tail is clearing up. It feels like straw now instead of a giant grease spot, the smell is slowly going away. Now the issue is getting her dry skin under control. LOL
