skin

I need some help here. We've been struggling with skin allergies for about 5 years but they are not getting better. I took him to the University of Tennessee for skin allergies testing. After 65 test spots only 2 came back - lanolin and gnats. I avoid any sprays and have added a fan to his room...

One of my show horses has some flaky spots on her neck. I have washed it with fungus shampoo, didn't work. I've washed her with dawn, she's been wormed.. It's very hot here so every evening after her workout I rinse her with the water hose.. Could this be drying her out? It's strange...
