Excess yawning?!

I've noticed that my horse yawns a lot...there will be times in the day where she just has one yawn after another.

I know that yawning is a sign of lack of oxygen and wondered if there is a horse problem linked to excess yawning or if she's just sleepy cause it's warm outside and she was in the sun?

Well, I don't know for sure, but I heard that excess yawning in people has been linked to regulating body temp. When we get a little too warm or whatever, we yawn as the sudden influx of air does something to cool us off.

Have no idea of that's true or anything, but if so, it could apply to horses,I suppose. Or...you just have a bored horse.

I YAWNED just reading this post...gosh their contagious!

I wouldn't think that it's anything to seriously worry about.

How warm is it ? How much water does the horse get? Also how may times do you take it out each day d how long do you take it out?
If these r answerd I may be able to find out why.

It could be the temperature- I doubt it's anything serious. :)

Actually I was told today it might be due to her selenium deficiency. It could be that or maybe I'm rubbing her in a spot she likes. Could be either way cause I only notice it when I take her into the barn to groom her or when I'm petting her.

I found this post amusing. Looks like you have a happy, relaxed horse to me I haven't heard of this before. That's quite funny. If you are concerned you should give your local vet a call. I'm sure they will be more than happy to answer your question

Like this???........He did five or six in a row after a hard lesson. I've also been told it's a stress relief, but who know's.

Is he showing signs of stress like pacing? Ticks?. Is he eating properly? Has he been acting unusually?

I Had a horse to a Vet a few years ago for mild choke, She told me that yawning is a horses way of relieving STRESS!!
