Hi All. Just wondering if I can pick the communal HHO brain, please? It's another scabby leg question!

We have a 15hh cob-x companion horse, who is 22 and only in very light work (like a gentle hack once a month, nothing more). She's out 24/7 in a 2 acre field (hilly with boggy and dry areas), only stabled when the others are in for work or the vet/farrier is there. She's in really good health, keeps weight well (a bit too well if you ask me), no problems with feet, skin etc. I was doing a normal quick field check on Saturday and noticed a large, red area on her foreleg, and thought o-oh, mud fever, here we go... I started to clean the area off with a soft cloth, and big chunks of hair were coming away in my hand. I did the best I could at the time, put on some sudocreme and the usual pig oil on her lower legs, and left her be. On Sunday, I brought her into the stable, washed and cleaned her legs with hibiscrub, and noticed some more red, sore, hairless areas on her other legs too. Some are small, isolated, round patches. Some are areas with thick hair. I've not noticed her nibbling/scratching or even stomping her feet though - their field is right opposite my kitchen window, so I do stand and stare at them quite often!

The question, is this... Are we talking mud fever? Or mallenders/sallanders? Or even ringworm? And how do I continue to treat it? The sores are nowhere near her heels, which is where I've had MF previously with other horses. Her feather isn't particularly thick. The pig oil I'm using at the moment has added sulphur - is that causing the problem, or will that be helping? I've known her about 5 years now (she's been at ours for nearly a year, previously at a livery where my mare used to be), and to my knowledge, she hasn't had this before. And most importantly, do I need to call the vet? She doesn't seem to be in any discomfort but the patches just look incredibly painful - not infected (to my untrained eye), just red and sore.

I put her out by herself in the sand turn-out last night in order to keep her legs clean and dry. This morning, the cream was still on, but I topped it up anyway. Do I continue with basic treatment with sudocreme and pig oil and sulphur, or buy something more specific? If so, what?

Thanks all.

They aren’t that ‘usual’ (not what I expected reading the post actually) so I probably would get a vet to see them TBH.

Fwiw I wouldn’t use pig oil on that, I’d add sulphur to the sudocreme if you have them separately rather than pre mixed.

Ask your vet for some flamazine ointment. Where there is infection sudocreme can seal it in and it will pop out eleswhere so making it worse.

Ugh!! That's what I was worried about. Ok, thanks both. I'll call the vet.

Looks very sore! What I tend to do on mystery patches is treat one with flamazine the other with anti fungal and see which one gets better. If in doubt though I would ring the vet.

I'm sorry your girl is going through this but like others that isn't what I was expecting to see! I was definitely thinking mites but these don't look right. I'd get vet too.

Thanks everyone.

They're looking a bit better this evening but still a few new clumps of hair coming out.

I have emailed the vet with photos so I'll chase up and speak with them first thing in the morning.

My immediate reaction was it’s a reaction to the sulphur as they almost look like burns. Deffo don’t put anything on her legs bar what the vet will give you.

So... the vet thinks it is likely to be Leukocytoclastic vasculitis. Apparently it's not an infection but more of an auto-immune response. Possibly linked to UV - all of the sores are on white bits of her legs - which I find hysterical, as there hasn't been much UV in Scotland in January!! I have to clip her legs, wash again with hibiscrub, apply topical steroid cream, and box rest her. Oh joy.

Hmm...

Anyone had any experiences of this?

I'll let you know how we get on...

Doesn’t always need much UV unfortunately.
Adorable Alice has made some posts about dealing with it and I have a couple of friends who have found silver whinnies helpful for it too iirc.

Sultan was prone to it in his white legs. He wore turnout chaps in the winter and sun/fly chaps in the summer so he never went out with bare legs as would burn within 30mins.

Quick update on the mysterious scabby legs...

I hibiscrubbed and clipped her legs last night by torchlight (yes, resulting in a fantastically neat job, please don't judge me on my clipping skills!) and took more photos. The lesions don't seem to have increased in size, and they seem less red and angry. I'm using the topical steroid gel prescribed by the vet, and keeping her on box rest, which is horrendous, as she's used to being out 24/7. I kept another horse in beside her last night, which I think she appreciated - she definitely slept well, judging from the flatness of her bed and the shavings in her tail!

I'm thinking turnout boots for the future, and maybe just turning her out at night for the first wee while. Sensible?

Fingers crossed this is the end of it, she heals well and fast so she can go back out with her pals again.

My friends horse has this and she generally stays in by day out by night - as with yours there doesn’t even seem to need much sun for it to flare up! I’m not sure there is much to be done bar management and watching the weather for uv readings (does the weather do that??)

Those legs look a lot better. Just to add a couple of points: has there been any change in feed, either up, down or different. Or any change in grass? There has been stuff written about hypersensitivity being caused by a reaction to rye grass or to alfalfa for example. Once I had a horse who had grumbling mudfever for around six months and it was only after I went to Tom Beech to rectify a performance issue that the mudfever disappeared. I'm not saying for one minute that your 22 year old living out has any performance stress ( unless its arthritic) but it might be worth widening your focus just in case even if its just a simple vitamin deficiency.

First of all I'd get vet for a correct diagnosis, if it is mud fever I have been battling with it since the summer and out of all the things I tried the only thing that helped was E45 cream not the lotion.

I would also think about testing for PPID as skin issues can be a symptom. Cut a long story short, I changed my horses meds for ppid and now he's on the correct dose all his issues have dramatically improved. It could be that she has PPID
