I had a guide horse when I was younger BUT it was a working ranch horse who happened to be really good at understanding I was blind & would fall into prairie dog holes by accident. I was around 3-8 years old at the time. My mom said he would walk with me constantly and push me away from anything dangerous. So yes and no? He wasn’t specifically trained for that but he happened to be a worry wart over his owners (my mom) kid. My mom also didn’t bother with getting me cane skills or anything for years because he was so good at it & bringing a new animal to train simply wouldn’t have worked with the cattle ranching schedule at the time. I’m currently looking into guide dogs though I’ll be switching back to a dual trained horse when I move back on the ranch in the far, far future.

I do not know but was also curious.

Wouldn't it smell really bad though?

I believe the organisation in the US is called the guide horse foundation.

There might be a couple of them in the UK, but we are such a small densely populated island that really there aren’t that many blind people who could benefit from one.
If I lived in a rural environment though I would be interested.
Also over here they’re not legally allowed to ride in a taxi.

www.guidehorse.org used to be the site I think.

I know a guy he’s totally blind and live on a farm. He has one, otherwise I think. He uses a cane?? It’s cool he was telling us all about it. I think he trained the horses himself though.

I am aware of a couple but the blind person had to train the horse themselves. I just know that one of the core issues is transporting them especially if you have another large mobility aid like a wheelchair, since unlike a dog they require a larger car and often end up transported in where wheelchairs would be. Space constraints also make public transportation to be much more unreliable, and rideshare apps or taxi are often unable to accommodate a miniature horse like they could a dog since miniature horses can't tuck.

I didn't know that guide horses were still a thing. I heard about them a long time ago, but that was when I was very young. Now my curiosity is getting the better of me...

It seems like there are a lot of videos on YouTube about them... maybe one talks about where the horse came from

When I was in school, I knew someone, who had a guide horse for a while. As far as I remember, that was some kind of pilot project. But that was more than 20 years ago.
As far as I remember, it did not go so well. That person had problems controlling the horse. I remember, that it ran away from her, when she was in a mall at some point.
To be quite honest, I never understood, how a guide horse is supposed to work anyway. Wouldn’t you need a really big place to live in?
