One of my memories that the recent death of our Pom, Tanner, (see pets forum) was the relationship he had with one of our neighbors horses. We nicknamed him "Moby" because he was big and white and he kicked Tanner once. (Tanner was being protective of his domain and skattled his bad self across 200 yards of meadow to confront him) Neighbor heard the barking and saw Tanner sail about 30' across the pasture, he thought for sure that little 10# furball was dead. He seemed ok, limped a little more than usual for a week or so. So Tanner was his " "Ahab". My wife commented she had not seen Moby lately and wondered what had happened, so she contacted another neighbor and found that Moby had not only died but did so in an unusual manner: couple months ago, with the owners out in the pasture, he took off on a flat out gallop, and slammed chest first into a post on the far side of the pasture. He was dead by the time they got to him. He .was in good health, no known issues. The only thing was, in the 6 or so years they lived next to us, I've only seen them ride him or either of the other two horses they have once. They appear to be treated well. Food water shelter and all. But why would he do that?
