Opinions are like bum holes, everyone has one.
I would feed something like MaxGut health. It could easily be grass issues with gut and you have nothing to lose trying it for a couple of weeks. Grass and sugars can do funny things to them.
I moved yard because of this problem. It started on our previous yard. So I moved yard summer last yearHow long ago did you change yard? Has this all started since you moved?
So sorry you’re also going through thisI’m having the same problem as you. Naturally anxious horse (didn’t have the best set up on his previous home, which I think has done a fair bit of mental damage). He’s normally fine, not great to solo hack but ok in company and schools nicely. Chomps a lot but that seems to have been a lifelong habit.
However, last three months he has been an unpredictable nightmare, culminating in a broncing session this morning that very nearly had me on the floor. I’m going to get the vet to give him the once over, if nothing obvious found then scope for ulcers (given anxiety levels and the explosiveness), re-check saddle etc. Instinctively though I think it is linked to the rapid grass growth as it’s worse after rain and this is the lushest grass we’ve had in the time he’s been with us.
He’s muzzled and in at night in soaked hay but it doesn’t seem to be enough
So not a lot to recommend but just to say I feel your frustration!
When we ride, he starts off fine, but gets more and more tense, the more we do. Then the explosive spooks start when he’s tense. He’s a naturally hot horse, so maybe that’s a training issue that I need to work on?
We are surrounded by wildlife in this area. Especially deer.
I’ve had this conversation with my vet, who doesn’t think there’s a problem as the horse can be fine for weeks/months at a time. And that physical issue of that kind would be apparent more frequently.I'm really sorry but that sounds like a physical pain issue to me. The build up to an explosion is characteristic of a stoic horse who holds it together and holds it together until he just can't any more.,
I know your vets have ruled out pain because they can't see anything on any of the diagnostics, but not all problems can be found with the techniques available. Has his spine been x rayed, neck and back?
Has anyone suggested Lymes disease?
