I was reading a post in the chat forum and got to thinking about this. For some reason my horses want to kill my dogs. The dogs have never bothered the horses at all. Where I bought my horse had a dog that was out with them while we were riding him all the time and my horse never even looked at him. Vinnie (horse) was fine with my dogs until I bought Starbuck for my wife. He has never liked dogs that I can tell. Any thoughts?
