I have a three year old Missouri Foxtrotter, and she has been having skin problems for a year. Her ears are constantly scabby, and she recently started itching the base of her tail. I live in Florida, so the bugs here are a problem. But even with a fly mask, garlic, and fly spray she keeps itching. Now that it is winter, I am thinking that it is her grain that has has been bothering her. I am feeding her Safe Choice. 14% pellet, I try to stay away from extra sugars. It has wheat and corn in it; which I heard is the number one thing horses are allergic to. If you have any ideas of what this could be, please let me know!
