I went to the barn today to check out and clean the scab that I found a week ago. I think one of the other horses nipped at her and just took the hair off and a little scabbing. I was brushing out her mane and I noticed that there was some dandruff and then the hair started FALLING out in huge clumps. I stopped brushing around that area and didn't find any other spots that were that severe.
Her tail is fine and I didn't use it on her forelock so I'm not worried about that. I have attached pictures so you guys can have an idea of what it looks like. The pics were taken on my phone so they aren't the best. The larger scab is from when she got bitten and lost the hair.
I didn't think she was allergic to MTG because this is the first time I seen anything like this before. She isn't sore around the area because I was brushing her mane, and then I softly touched the area to find any tenderness.
If you guys have any information or suggestions that would be great! I know there are a lot of threads about MTG but I didn't see anything like this before.
