"Roaring" (Left Recurrent Laryngeal Hemiplegia)

I tried to find something on Internet about what can cause it and basically could find nothing scientifically proven. So I wonder if someone came across/owns the horse with this condition and may share some info. Thanks!

Are we talking roaring as in when working the horse sounds like its gasping? As far as I'm aware its generally found in bigger horses where they don't have enough room to get the air in and out, which produces the roaring side, or if their throat latch area is too muscled/fat it can happen. A friend's horse had an operation for this, didn't help at all.

Doey used to roar in canter until I built his fitness up and then he had no more problems.

Hope we're on the same track ;D

As far as I know roaring is not serious and does not severely limit the horse's ability to perform. I used to be a 3day eventer and remember seeing a big appy competing very succesfully. He was a roarer and you ccould hear him from a ways off, but he did fine. They used a big breathe right type strip over his nose to help him out, too.

Duffy, yes, I think we are on same page. I think it can cause further complications too. But I was wondering what causes it in 1st place. :)

I have heard there are two different ways to become a roarer. The vet said 1. The horse is born with it and its (in more words then this) a malfuction in the way there air flows. 2. Is physical damage causing a blockage in the airway that will cause difficulty breathing without proper conditioning.

The first one I was told was not limiting as long as the horse was fit for the task.the other I am not sure. I know my vet considers my horse denny to be a roarer because of the trauma his head has been in and has limited use of his right airway due to the blockage. I can try and get pics this weekend but its only considered roaring bc it effects the airway and causes him to roar. Or so I was told. But I have found out with proper conditioning it doesn't affect him as much. And is getting easier for him and has slowly decreased in the roaring at walk and trot.

I only know its fairly common in big horses as they have to have so much air, and one tube is either thinner or not as strong as the other.

As mentioned, if the horse is built up fitness wise carefully there shouldn't be much problems and it shouldn't inhibit the horse too much...

I don't know too much about it so will be Subbing to see what other people say ^^

Actually another thing I'm curious about... What is the displacement of the soft palate/how that can happen? The reason is that although roaring in itself may be manageable, the physical problem of the displacement complicates things. The vet said that the horse would be totally useless for any kind of performance riding.

I don't know much about it. My vet has told me as long as they are conditioned and learn how to breath to get the max air they can overcome it. Its just a matter of them figuring out how to control their breathing... she used th example of when humans train for running they hold there breaths a few seconds instead of huffing.. that's what the horse has to kinda figure out.
Not sure though... since all my info is based on a horse who has damage causing the blockage and not just the normal roaring condition.

I think it depends on the horse and the contributing factor. I have a friend with a horse that roars. He suffered some sort of illness, I am GEUSSING strangles but I actually don't know. I know he ran a high fever and the trainer gave him some type of antibiotics. (this is where I assume it was strangles, the other assumption is that the antibiotics caused ******* strangles). I can't remember all the details and it was a bit of a hush hush situation anyway. (I think because the trainer may have screwed up).

The horse ended up getting put on a very strong medication (started with a D) that was supposed to help him breath. I think there may have been an overdosage. Anyway the horse now has a paralzied larynx and maybe even a lung. Not sure. He wasn't supposed to survive but he did. He is used for light trail riding but would be disqualified in any show.

He handles the work that is thrown at him very well but I do know that his owner is careful and really pays attention to his breathing and heart rate when working him. As far as I know she's never had an issue but I would say that saying that it doesn't really effect them is somewhat of a half-truth.

Does anyone know if there is a shot or a medication that can control the roaring? (Just curious)

There is a girl in my old 4h club who had a horse who was a "roarer". They actually went as far as to get surgery to correct it. Thousands of dollars,
