Hey I am excited this is my specialty! I have had to teach I don't know how many horses to slow down a gait. So this is going to be good.
So the first thing you want to do is invision a four leaf clover. Follow the leaves well this is hard to explain with out a picuter so never mind that and we will try a new method how bout......
Everytime your horse speeds up do a small circle it will take a few tries untill there is perminent progess but trust me it works so everytime this horse speeds up do a small circle untill he/she slows down! And if she doesnt slow down make her engage at the canter by sliding your leg back and asking her to move her hinds end over a little. It makes the work harder and then you horse will slow down. Let me know if that doesnt work and then I will give you a few more ideas.[/b]
Yep sure do like my horse more than you.... Peace!
