My 19 y/o clyde/QH gelding has developed a persistant case of scratches each summer for the past 3 years, getting worse and starting earlier in the season each year. This year I’ve started to notice scabs climbing up his legs above the pastern.
He has 4 high white socks, and the scratches clear up like clockwork in the fall once we get frost again. Even through the muddy/wet fall and spring seasons his heels look great.
I’ve tried basically any and all medicated ointments, scrubbing with antiseptic washes, zinc ointments, topicals, etc. but this stuff won’t stop cropping up. It’s driving me nuts, and even though it’s pretty minor and never causes infection or soundness issues.
Has anyone ever heard of scratches only occurring in summer heat? I’m not sure if this is bug related or maybe some kind of UV or humidity sensitivity.
