Centaur I am so sorry to hear it.
He had a good long life. Sometimes, I have observed, when a horse is near the end they wander, walk, stray --- if they are able.
The two of you had a great life, you could not have asked for more.
Perhaps he was ready to go.

I had 2 horses that did that. Oddly enough, they both favored the same tree, standing under it all day long. These horses didn't live here at the same time so they weren't copying each other.
