The equine hospital was a great place. Lots of horses pulling up and friendly owners. Everyone spoke highly of the vets and the facility and were so happy to have it available. It was 146 miles, one way for us. We arrived early and they fit us in. Since it is a hot day, that was thoughtful of them. They offered an outdoor stall for John Henry, but he was content in the roomy trailer.
The vet came into the private exam room and said they were so excited to meet a pony named John Henry! Wasn't that thoughtful of him? He always referred to him by name, and never called him "the horse".
My sister told his symptoms. He has been slowing down, not walking out in harness, not wanting to trot, for about 8 months. The last 7 months he makes a sort of grunt sound when he is simply being led. The last time we went out to drive together, we had to cut the drive short after just a few blocks and she got out to lessen the weight and lead him home. He had a hard time making it home. She thought maybe it was arthritis slowing him down, or allergy affecting his breathing.
The vet said it could be a polyp or it could be a collapsed larynx. He said a collapsed larynx is only found in ponies. He's never seen a big horse with it. It is a "pony thing". Some dogs can have it. We had never heard of such a thing.
They put a twitch on John Henry, very quietly and carefully, and he stood like the stoic, well-mannered stallion he has always been. The scope went into the nostril. We watched everything on the monitor. He did the larynx first and then the esophagus.
It was not good news. It was not a polyp in the esophagus but a collapsed larynx. The scope revealed the larynx collapsed almost all the way, 80% collapsed. If the larynx had only been affected in the neck, doing exterior stents may have been an option. But not when the damage was down to the chest. (Interior stents are not available in equines yet; for some reason vets do not know, equines build up granulation around stents and they don't last very long.)
It is a progressive disease and they seem to think it is something hereditary. It is not reversible and they cannot predict how quickly it could progress. There is no medication for it, only a drug that dilates the capillaries in the lungs so they can use the limited air better. He did not recommend that for John Henry. He warned my sister that the larynx could totally collapse some day and she could find him thrashing in a panic because he could not breathe; unconscious; or even dead in his stall.
They discussed euthanasia and the vet said he suggests making a list of 3 things John Henry enjoys. If he stops enjoying any of those 3 things someday, then it might be time to consider that option. My sister thought about having to deprive him of food, the idea that the larynx might collapse when he was alone and she would find him thrashing in panic, or even coming out to find him dead. She decided not to bring him home.
Wacrapas John Henry was 20. He introduced small children to the wonderful world of horses by visits to school, the Fair, and giving cart rides. Children in his neighborhood called him by name when he went down the street in harness. He was a good, kind boy and never gave a speck of trouble, until this.
I'm attaching the comments and recommendations for care in case anyone else thinks he might have this problem with his horse.
