Sudden Death

O lost an eleven year old gelding this past week. I care a lot for my horses and really hated loosing my main ride. I’m trying to understand what happened and what I might have done different.
This gelding has been a real goer for all the years I’ve ridden him. Close to a 1000 trail miles each year. He liked to lead out and moved at a brisk pace with out needing a lot of encouragement.

This spring I two mare coming off maternity leave, that were overweight and I committed to spending more time riding them to work on getting them in shape. My gelding got some time off. Getting out for a trail ride once every two to three weeks. Instead of weekly. I noticed in March-April time frame that he was slowing down. Less willing to lead, and huffing-puffing a little more on climbs. I just kinda figured he was loosing his conditioning since I was working the fat mares.

July he was definitely not himself and more of bring up the rear and huff and puff.
So I decided I needed to more time into riding him and get him back in shape. I took him out for a solo ride, early morning, So temps were high 70’s Nothing terrible. He didn’t want to move out. So I just let him dog walk the trail. About 2 1/2 miles out, I decided he must not be feeling well it would take all day to the 13-14 mile loop I had planned on and I re-routed our course so we were headed back to the trailer. About 3 miles in he stopped and just really didn’t want to move forward, So I got off and was leading him. About every 100 yards he would stop and want a blow. This was a pretty level trail. Not that hard of work. Something he normally would have trotted and not broke a sweat. At the third time he stopped, the teetered a couple times, like he was having trouble controlling his back legs and crashed to the ground and was basically gone. Very shallow breathing, So I quickly undid the girth and pulled the bridle. He showed no awareness of his surroundings and stopped breathing a short time later.

I suspect he must of had a heart condition or aneurism. Something that caused the slow down in the months before and then the sudden death. I’ve done endurance and competitive trail and think I have a reasonable ability to look at a horse’s condition. And I would have never thrown a saddle on him, if I suspected he was that fragile. Standing in my back yard with my herd of horses, You would never have noticed he was slowing down. But apparently 3 miles of walking was enough to trigger the event.

I’m kinda looking back trying to understand what symptom I missed and what a vet might have been able to do to treat something like this. If there was a treatment. Any ideas?

It sounds almost like congestive heart failure with the exercise intolerance, and that can cause artery rupture and sudden death, but generally there clearer signs that the horse is having issues (ventral edema for example). It may just be one of those terrible fluke things that happen even when you do everything right.

I’m so so sorry. Everything you did was in keeping with how you treat an 11 year old horse when he’s been off work awhile. Horses are so stoic. It could have been a lot of things.

It sounds like everything you did was perfectly reasonable. Sometimes bad things just happen, and I’m so sorry for your loss. To have it happen on a trail would be even worse than just having it happen at home.

You don’t say the last time a vet had seen him. It’s possible they would have heard a murmur or seen other signs in a routine TPR.

The only way to know for sure is of course a necropsy. Of course, it’s expensive and I assume no longer an option.

I’m curious to hear what a vet would say but I can’t imagine that a 3 mile walk on a nice day did anything more than bring the timing forward. I don’t know how much they can fix in horses with medication that would make the difference around whether it’s safe to ride.

I’m just so sorry - that sounds absolutely devastating.

I’m so sorry for your loss. It’s absolutely shocking when they go like that. Years ago I had one go from what the vet thought was an aneurysm and it happened so fast I could barely get her out of the barn. Hugs sent your way.

I’m heading up to Tetons in a couple of weeks, So he had been into the Vet a week before his death to get his Health Certificate, Coggins etc. I know that is a casual inspection of the horse being healthy. But nothing was noticed by the Vet at that time.

I had a friend who had horse die in similar fashion 20 years ago. I remember asking my Vet about it back then, just being curious and that vet suggest a ruptured Aorta. So I kinda guessed the same for this horse.

Oh how awful, I’m so, so sorry.

Out of all the riders I know, the endurance riders are the ones most in tune with their horses norms. This sounds like there was absolutely nothing could have prepared you for this, particularly with the vet having seen him the week prior.

Big hugs :purple_heart:

I’m so sorry for your loss. I don’t think you missed anything or could have changed the course of events; just one of those terrible random things that knocks us sideways. Many years ago a friend had a gelding in his mid-teens (who seemed to be in the prime of life, fit, happy, ridden regularly) drop dead under her while she was cantering on a trail. She didn’t have him necropsied but most likely an aortic dissection. Absolutely shocking, and she was lucky she wasn’t injured in the event.

Sounds like your guy was a great partner. Condolences and hugs to you.

I’m so sorry for your loss.

I doubt there was anything you could have done. Horses often have irregularities in their heart rhythms. My vets have often mentioned it as present and nothing to worry about with my horses.

It does sound like an aneurysm that blew.
My condolences.
Nothing you could have done to prevent it.

One year ago I went out to my barn to feed breakfast and found my beloved 19 year old paint gelding lying dead in his paddock. I will never really recover from that trauma.
I had been out in the barn late the night before, and mr
Paint was perfectly fine.
After grieving a few weeks called his breeder in hopes I could find another horse like him
Told breeder what had happened and he told me my guy’s sire died the same way, no warning.
You have had a trauma, take care of yourself.

I’m so sorry, that sounds traumatizing.

I had a seemingly healthy 9 year old horse drop dead in what the vet guessed was probably a ruptured aorta. I found her down where she wouldn’t have laid down, with no signs of rolling or thrashing around her. In her case, there were no signs at all leading up to it.

It doesn’t sound like you missed anything or did anything wrong. Who would ever think that tiredness in a young horse was anything other than being out of shape due to the time off? It’s easy to blame yourself in hindsight, but you did nothing wrong given the facts you had at the time.

So very sorry you lost your horse.

Here are a couple clips from that last ride. When I first got on him and rode past the trailer heading for the trail head and a mile down trail. You can see that in either post we are not rushing or pushing hard. Just a walk in the woods. I guess it was just one of those freak thing that happen. Horses always seem to be looking for a way to get hurt or die. Thanks for everybody’s response. I’m 73 years old and my gelding was 11, I was kinda hoping he could be my last horse and carry me into my 80’s. So I wouldn’t be starting a new horse at my age.

I’m so sorry :heart:

I am so sorry you lost your beautiful gelding this way.

What a grand looking gentleman from where you sit. I am so deeply sorry. I agree on it being a heart issue as others have said. You were with him at the end, so there’s that as a comfort.

He looks so happy to be out with you, with his ears forward and relaxed! I am so sorry you had this happen, I can’t even imagine how traumatized you must be. Do take care with yourself, this really is heartbreaking.

I’m so sorry.

I’m thinking maybe congestive heart failure as well? The ‘huffing/puffing’ and the gradually getting worse over time, makes me wonder if that could be it.

Big hugs and jingles to you. Horses are stoic animals. It may have been worse than he let you know.
