On his left side on the cannon. The cut is more like a scrap....but just kind a worried it is still bothering him after over a week. It is not hot to the touch just scabby. He actually scraped it on my friends trailer when he was giving us a hard time loading. I have some special topical flush for horses. I started using it on him. He is scheduled to go to the trainers in 2 days and just wanted some input.
