I'm guessing you mean Massage Therapy. There are many programs that offer this, and each one has its own requirement. A good knowledge of the anatomy and physiology of the horse is a must; a knowledge of diseases and how each affects the body is also very valuable.
If you can't get equine-specific classes, take a good foundation of Biology and/or animal health courses. Many concepts in anatomy and physiology can be used for several species.

If you want to be an ecologist (like me) you should take science courses such as Physical Science, Biology, Chemistry, Physics, Environmental Science, Earth and Space Science, Geography: math classes including geometry, algebra, pre-calc., statistics: some technology and engineering classes: government classes such as government and politics, psychology [and others that your school offers]: English courses[that should be required for you]: maybe some physical education courses to keep you motivated if you're the kind of ecologist that will be physically active all day long: and those courses should make you become a successful ecologist. :)
