In theory it should work. I havent seen one being used personally. the only thing I would be afraid of is the front end hoping around or moving on a trailer with no sides. I think you would be better off with tieing down two tires. JMO
If you are talking about the Louisianna Trailer dog I have used it for several years. I have not used the one that attaches to your hitch, but I can tell you the one that attaches to your trailer is absolutely the strongest and best way to trailer an atv that I have ever used. Their customer service is A-1 also!
