Remember I had been saying one of the horses in my pair was not acting right? I found a bump on his tail, just a raised area, not large, that did not seem to bother him when I touched it, so I ignored it.
He had been so bad one evening last week that I just circled back to the barn and unhitched. So the next day, hitching him up single to see if he was different, as I put the crupper on he leapt forward about a foot, as I had brushed that bump and it popped open.
So the vet is coming this morning to remove and test it.
He has been telling me something was wrong, and I have TRIED to listen...he may be a bobtail Arabian after this, lol.
