I will be unable to check this later than this evening since I'll be heading back up to camp and won't have internet access until next weekend so if you have information/links for me, please post them as soon as possible. :)
Disclaimer: This is one of the camp horses that I'm in charge of. We're renting these horses from an outfitter and our contract with the horse's owner does not include anything medical so we need their permission to get a vet out and they are refusing to grant us that permission. They are also being very hesitant to remove this horse from us (they have interesting ideas about medical care- as in, they thought one of their horses was foundering [visually diagnosed] and instead of allowing us to have a vet out, they just had us take her off grass and bute her up and just continue doing that for as long as necessary for her to be sound again, I later discovered pretty severe mudfever in her fetlock area that was causing the lameness which I'm now treating) and I refuse to have an injured horse in my care that I'm doing nothing for, so I need your help. If she were mine the vet would have been out as soon as I found this.
The question: The mare in question has a quarter sized abscess under her chin. It appears to have popped and is draining pus everyday. We've been treating it daily for the last three days (since I discovered it) and on the first day it smelled AWFUL but now it has hardly a smell at all, which I figure is a good sign.
I've been treating it by washing all the gunk off of it with a soft cloth, warm water, and an antibacterial shampoo for soap. Then, once all the gunk is gone and the hole is clean (for all intents and purposes, it looks like a huge zit/volcano), I've been smearing nitrofurazone on it and letting her out.
She's acting fine so I don't think she has an infection of anything...
Is there anything more I should/can be doing?
I really appreciate the help!
And so you know, I'm doing what I can about changing the horse situation. I've convinced the camp director to look into using a different outfitter for next year but it's a difficult process since the outfitter we're using is the main one in the area and since the camp director sees nothing wrong with just letting sick animals be until they die. But I'm doing what I can and trying to change that cycle of thought.
