Weird Skin Issue, Possible reaction to tick bites?
I recently noticed odd looking scabs on my horses legs, chest and under his skin. I've done some research online and I *think* its a reaction to tick bites. He's a rescue and around 200lbs underweight, so I have him pasture boarded for constant grazing.
The scab things are a greenish/yellow in color, look clustered and are on there pretty good. I included an attached picture.
I was wondering if anyone else has had experience with this and what they did for it. Any insight would be greatly appreciated. Thanks! :)
