I have had several request to do some conformation articles. So I am going to stay very basic and help you understand that if your horse's conformtion is off why they work good one run and may be off the next run or why different ground affects horse's.
I would like to say, a horse can be the best looking one in the world, but without a willing attitude and heart no conformation is going to help. A horse has got to have the want to and be able to control their temper under pressure situtations. You also have to deal with the emotions of each horse so you now how to work with them. Some horse's love pressure and some get stressed out when to much pressure is put on them and have to be taught a little bit slower.
Over riding a horse will work aganist you on most horse's. A horse can run free on their own and learn what cues are for rate and run.
Bad conformation causes body soreness and pain in places you would never even think about.
What will we go over?
