I'm not sure what they are, so I called my vet ASAP! When the nurse answered I told her about it, and she said the DR would need to see her ASAP and I totally agree. Well he won't come out for just one horse, so I had to try a different vet. So I called the next closest vet, and he said he thought it might be lice so I should bath her, and if that didn't help, he would come see her.
I took some pictures and would like to hear your thoughts on what it is. I'm not sure if it's rain rot, because I've never had to deal with this type of thing before, but I doubt its rain rot because they have access to the barn 24/7.
She is also losing hair on her face, on top of her head, and on one of her ears. This hair loss isn't accompanied by scabs though, it just looks as if she has been rubbing it off. I didn't get pictures of that, but I will tomorrow and post them on here.
Could it be any type of allergic reaction? She has been wormed with safeguard and that was about two weeks ago. If you need to know anything else, feel free to ask.
Here are some pictures. I only took pictures of the first four spots I found. The ones I found today are larger than the ones I found yesterday.
