How to PREVENT summer sores

Some might remember last year my Friesian gelding had AWFUL summer sores on a front and a hind fetlock. It was stressful, expensive, frustrating, just about every bad thing. They took three months to fully heal and kept getting re-opened and reinfected. He had to be on antibiotics twice. And by then end of it my usually sweet gelding was kicking out and not cooperating for medicating and bandaging and ended up getting sent to the vet’s clinic to get them healed. So needless to say something that we do not want to repeat ever again!!

I was looking through my pictures from last year and it was late May/early June when the sores first appeared last year. So I want to try and do everything I can to make sure they don’t happen. He had a fecal count done last month which was zero. He was dewormed last week with ivermectin, which is supposed the dewormer that kills the parasites that cause summer sores. I’ve already started fly spraying him before he goes out at night. The barn owner will be starting her feed-thru fly control and fly predators soon. For anyone who has ever had experience with the hell on earth that is summer sores, what else can I be doing now to prevent this??

Search this forum for the Onchocerca (Neck Threadworm) thread. It’s huge. Follow the Double Dose Equimax protocol and see what happens. Won’t hurt to try.

Be on the lookout for little scratches or cuts or injuries which break the skin and expose tissue. Then make sure to keep ointment and fly spray on them or covered if possible. Daily or better yet, twice daily fly spray with a good quality spray can help also. You really need to be diligent in spotting breaks in the skin.

Even minor itching on a fence post or tree can scrape open skin and then a fly gets on it and deposits eggs. This is why you need to check daily for these seemingly minor scratches. If the scratch/abrasion doesn’t start to heal over immediately, apply plain ivermectin to the sore daily until healed. And again, loads of fly spray.

My vet had a case (here in NC :eek: ), on which she consulted with one of the leading parasitologists whose name I constantly forget :frowning: for a SS situation. What finally got things resolved was a 4x dose of ivermectin. I’m not saying “do that”, just saying that’s what ended up working to really clear up the habronema which was clearly causing troubles.

Beyond that, as Marla said, you’ve just got to stay really on top of finding and covering any and all broken skin.

The 4x dose of ivermectin is what we did to treat last summer when the sores got bad. I don’t want to over-deworm him especially as his fecal was 0. Maybe I’ll do another round when we start getting hot weather.

I honestly don’t know if they started internally or externally for him. From what I understand, the horse gets a small cut or abrasion and then the parasites from the stomach are transmitted by flies into the wound (someone correct me if I’m wrong here).

The sores started when he came in one morning with a small abrasion on his hind fetlock. It looked like an abrasion maybe from laying down. He goes in turnout from 6pm-6am and is in a stall 6am-6pm so maybe from sleeping outside like a goober instead of in his stall? But the weird thing is he has never had fetlock sores before and you’d think if he was getting them laying down in turnout, it would happen all year round right? But who knows. I’ve tried fetlock shields before when the summer sores were first starting and I thought they were fetlock/bed sores but the ones I got moved around too much and rubbed his fur off. He is a Friesian and has a lot of feathering and it think the feathering prevents them from getting a snug fit.
