I thought of pigeon fever, I have seen two cases of pigeon fever, and it is not like either case I seen, but I will do some reading to see if maybe this is an atypical type of pigeon fever.

I think allergic reaction.

E-mail Professor Derek Knottenbelt at The University of Liverpool Equiine Hospital with a full description and photos. He's a world renowned skin specialist and he just loves an interesting case. He travels all over the world, so if you receive no quick reply, that's why! His email address is:

I had an allergy case that had baffled my equine vets for two years resolved by him in just two (free) phone calls and one email.

Apart from that, I would be talking to your vet about a course of steroids.

Good luck with it.

While rain rot CAN be bacterial in nature, more often it is fungal, and antibiotics therefore will do nothing.

However, I'm feeling chances are this is an allergy. Pigeon fever, from reading, doesn't quite fit, but I have seen and heard of stranger allergic reactions - a horse that presented with ERU [moon blindness], that in actual fact was severely allergic to oats [he was so allergic that his immune system started to attack his eyes; when oats were removed from his diet, his eyes went back to normal, and he lived another 15 years before being put to sleep due to an unrelated issue], is one example. Another I have heard of was allergic to something, I'm not sure what, and presented with sores on his coronets. Diarrhea is not unusual with a change in feed, even if it's just that the same kind of hay is coming from a different place. We also mustn't rule out the possibility that his feed is contaminated somehow.

I'm guessing allergic reaction, too. My horse is allergic to ticks and he gets swollen sores that ooze yellow serum and the hair comes right off, just like you described. Not nearly as widespread and severe though.

Good luck, I hope you guys figure it out!

Yes Id also have to suspect allergy at this point with runny poo and a skin reaction. The hay sounds like a possible culprit. Luckily, that is an easy fix if its turns out to be :)

Agree allergy reactions can present some nasty skin reactions with accompanying swelling & cellulitis.The Diarrhea is bothersome symptom,but with the skin lesions too he could be having a quite significant reaction to something he ate or may still be exposed too.Did the vet draw blood?This is affecting him systemically & at his age i'd be concerned about renal & liver functions.

I am hoping it is an allergy. We'll try taking him off the new hay ASAP, there is still some of the old hay left, Star can eat the old while the other horses get the new. I don't think he is reacting to a toxin because there is nothing in his environment that 5 other horses are not exposed to as well, and none of the other horses are displaying any problems.

Vet#1 did not draw blood, he diagnosed staph infection and began treatment accordingly, but Star is not responding to treatment.

Vets2&3 both want blood work done.

From the discussion I had with vet#2 and the research I have done on line, i am concerned about possible renal or liver problems.

Has he been wormed? Stomach worms can cause those symptoms if not treated.

what about mange? I've even seen dogs have allergic reactions to the mites that cause mange. Just a thought.

that was my thought there's been a lot of cases of pigeon fever in the southern state this year
