I recently bought a 10 year old Quarter Horse mare. I am teaching her the barrel pattern now and she is doing great. My only issue is that she has a problem transitioning from a trot to a lope. She does this really fast bouncy trot for a good distance before she can pick up her lope. Once we are into the lope, then it takes awhile for her to collect herself. Are there any exercises or any ways I can train her to pick up her lope immediately and then collect herself immediately? Thank you!
