My neighbor's horse Star, has developed a condition that is currently stumping three vets. One week ago he started with diarrhea, then began developing skin lesions that oozed sticky yellow serum until it hung off Star's coat in icicles all along the horse's topline and chest. Vet #1 put Star on a round of anti-biotics and gave him a medicated bath. Seven days later, the horse's condition has changed very little, the serum dripping has reduced some, but he has also developed severe swelling in his chest that seems to be draining down into the fore legs above the knees. When the weepy areas are disturbed(washing, rubbing) the hair peels off in chunks, the skin beneath is flaky and dry.
Vet#2 is a good friend of mine, we talked at length over the phone and I sent him blurry photo's shown below. He had few ideas.
Vet#3 was sent the photos as well but wouldn't comment until he sees the horse in person, set appointment for Saturday.
This photo is of a patch is missing hair, and is still weeping serum.
This is Star's topline, he has been wearing a blanket, so the serum has soaked into the blanket rather than hanging in icicles like it did before he was blanketed, but the extent of the lesions can be seen.
This is a patch that has lost the hair and is no longer weeping serum.
The photos of the swelling didn't turn out very well so I didn't post them. It is winter, very cold lately, so bugs really are out of the question. The horse is 18+yo. Any Ideas would be appreciated!
