We're coming into summer here in Australia, and as a result, we're getting some tropical weather coming through. Last week we had a day of torrential rain, but it stayed at around 30*C and has now just gotten warmer. I left my thoroughbred naked for this time, as he gets very hot if I put a waterproof on him, even if it is raining, in this heat.
Literally overnight, he has developed rain scald/rot. I fed him that night, ran my hand over his back and found him covered in scabs.
This isn't something I've had to deal with before, so I'm not 100% confident in dealing with it.
I have been told to pick all of the scabs off him to expose the bacteria to the air, and treat him with medicated shampoo.
I haven't been terribly successful at getting the scabs off, as he is a sensitive horse at the best of times and gets very agitated about the process. I have been dousing him in tea tree oil shampoo and concentrate, but it doesn't seem to be doing much for him.
Currently my once beautiful, sleek grey thoroughbred looks like a mangey mongrel
Any suggestions on how to treat this, and how to help the hair grow back? Summer has just started so his coat won't be shifting for another few months now!
