Nope, I'm thinking Sweet itch. Sweet itch is an allergic reaction caused by Midge fly bites. (Midges are TINY and you don't even know they exist!)About 30 % of horse nowadays have it. Mine does... when it starts to get warmer, he starts to lose chucks of hair like this. He also rubs on EVRYTHING because he itches so bad. Unfortunately there's no cure. AND they can develop the allergy later in life as well as early on. (My horse is 14 and it just started) You can alleviate the symptoms by weekly washings with aloe based shampoo and MTG. That's what I find works best.
Your horse looks just like mine! Have a vet look. I can almost guarantee that's what it is!!
Well, there is one thing to look for if ahearn is right about the summer itch (sweet itch) : The hair loss is due to your horse actually rubbing it off. Horses with summer itch scratch and rub themselves violently against other things like fences and trees because they itch so much. As a result, they rub off chunks of hair, and sometimes rub enough to make themselves bleed.
If your horse is like mine was, it has developed bumps under the hair and when you scratch the bumps off the hair goes too. Horses with rainrot don't really itch themselves like horses with summer itch do. The hair loss is due to the lumps falling off leaving little patches of bare skin.
Not so much, Tim. I disagree, My horse has it in spots where he CAN NOT reach to scratch in any position. ...ie. On the bottom of his chest, a lot on his belly, on his genitalia, etc. By definition, migde flies like to attack certain areas and that is where you see most infestations....around the base of the mane, the chest, the belly, the gentilalia, the buttocks, tail dock,etc.
It could definitely be rain rot, but don't rule out sweet/summer itch...
Im leaning more towards rain rot but I deffinatly wont rule out any possiblities I want the best for her so im going to order some mtg again or for now use some alcohol rub on it and see if that helps at all.
its definitely not rain rot...horses don't loose hair like that from rain rot. Rain rot is basically when the horses fur grows mold. My horse had a little case of it.
I just had to reply to this. Horses can loose their fur when they get rain rot. We've had plenty of cases at my barn. The worse was when we pulled the rain rot off, it bascially pulled his skin off and there was pus and everything underneath. So yeah, horses do loose fur when they get rain rot.
There are many different types of rain rot, all caused by fungus. Some look like black dust under the fur, some take small chunks and leave little bald spots, some bad cases can lose big patches of hair. Use a Betadine shampoo first, to kill and disinfect the area, and then you can treat it. MAKE SURE that you disinfect your brushes and wash any equipment that gets in the area, or you will give it right back to the horse or give it to others if you use the same brushes on other horses. I mix bleach and water and dunk my brushes in it to sterilize them, but rinse well and let them dry out in the sun so they don't irritate your horses skin later. Good luck!
