I have an older mare and all of the horses are starting to shed. When I went out tonight to feed them I noticed she had a large patch of fur missing on her side and other spots on her body... I looked to see if she was losing patches of fur all over and her fur just comes out in chunks all over her neck, belly, back, butt and legs... what could this be??
I know you can lose large patches of fur due to rainrot... but she didnt have any previous signs of rainrot and her fur looks healthy other than its falling out in chunks.
