So I recently moved my horse to a new barn and the day after he got off the trailer I noticed this new growth of stuff on his back leg. It's only on the one leg, only in this one spot and it hasnt really changed in the last 3 weeks. He's out in a dry paddock (we live in colorado) so it's not due to rain or soggy living conditions...Im pretty convinced he got it from another horse on the transport trailer.
I've washed it with chlorahex but it doesnt seem to do anything. I have a vet coming out to the barn for vaccines in two weeks so Im going to ask him about it then..but I was hoping someone on here might know what it is! He doesnt like you messing with it, but he isnt lame....it's very strange!
