The dog in the picture does not have ringworms. I'm in East Texas. Got some friends in La. They had that happen before. It was just like that and it was right after a hurricane come through, similar to your storm coming through.

It's some type of mosquito or insects that come through with the storm.....at least it was in our case. These guys did nothing and it went away. Allergy remedies might do the trick

I do get some ring worm from time to time. Just use Lamisil spray. About a week and it's gone.
