I have never seen a horse like this before so have no idea what it is. I thought it was maybe like mudfever so I washed her feet with hibiscrub but there were no scabs and like I say, they wern't too sore to touch and she was fidgiting because of the flies more than anything else. The midges had decended tonight and they were irritating her but that wouldn't cause her to scratch her heels bald would it? And it does look like she has been doing it all weekend, but I hadn't noticed her doing it before I went away.
Sorry for novel but, what is it and how do I treat/prevent it?? Thank you for any suggestions!
