Rusty rounds up the horses

I was watching these beautiful Belgian Horses when out of no where this small dog bolted into the horse ring. He chased after them and the horses tried to get away from the charging bully. Then the horses started to run after him but he was super fast! The owners said he does this all the time and he hasn't gotten stepped on yet, lol. The first time he does will probably be the last time:)
