Here is a link to a video highlighting two trimming techniques. Even though this video was produced in 2007 the basics remain the same. Both trimming techniques have been around a long time.
For anyone interested in exploring AEP and the HPT Method attending a hands-on course is a great start. I think it is important to know that this method has been taught to thousands of concerned horse owners and professionals for nearly 20 years. The HPT Method was included in an article published by the American Farriers Journal in November of 2002. The article was a review of the seven most common trims being taught around the world at that time. This method has stood the test of time and continues to help increase the quality of life our horses experience. I hope to see many of you at a hands-on course in the future. Best wishes.
