One evening about a week ago when I brought the horses into the barn I found the Arab / Saddlebred with this big sweating patch on her rump. It was sore to the touch but no apparent injury. The temps outside were near zero F. but the frost melted shortly once in the barn but the sweating continued. I blanketed her when I turned her out next morning to protect the wet area from frost bite. I have not seem anything like it in 30 years of life with horses.
The vet examined her and she had not seen this either with no apparent injury in a horse who is turned out in her paddock alone each day. The horse received Banamine for 3 days and then Previcox for 3 days. The sweating was gone in 3 days and no longer seemed sore.
Has anyone in the blogosphere seen anything like this?
