On the note of disorders, I decided to write about strangles. A few years ago, the place where I kept my mare had a bit of a strangles outbreak. Fortunately my mare was unaffected, but I still think it's important to know about strangles just in case.
The symptoms of strangles are usually a high temperature and abscesses under the jaw or around the throat. The abscesses will burst eventually but be warned-there's lots of pus, and it smells really bad... Anyway, strangles is a bacterial infection that usually affects younger horses. The treatment is an antibiotic that you can give to your horse after their nasty abscesses burst.
There is an intranasal strangles vaccination that I talked about in one of my vaccination posts. There's a lot of debate about whether or not you should actually give your young horse the vaccination, but I'll save that for another post!
