No he was just an old thoroughbred. I dont think people would stab horses out of jealousy but I do know there is a lot of bitching in the show world.A friend of mine wont even show in Shetland cause she cant stand it all. She takes hers down south and wins everything!I once found my horses head collar, which he wore all the time, cut patterns into. The blacksmith came that day and could not replicate the cuts or patterns with his knives! They must have used a stanley or something and then put it back on the horse! defintely think horses tails go for fly tying though. They do sell it in shops as well.
