I purchased a 5 yr old mare a year ago and found she was really green when purchased. She has good blood lines with Doc Bar and Poco Bueno in her lines. She is turning out to be a good ranch horse with two exceptions. Number One; she has a very rough gallop using her rear muscles to propel her. Number Two; when she jumps sage brush or ditches her jump ends with a rough rear action. I am getting up in age, so, when riding a 25 mile day or chasing after a cow this roughness gets real old fast! I have not had a horse that uses their rear muscles to this extent before. She seems to have good cow sense, good in all terrane with no fear, so I would like to keep her. BUT! Does anyone know how to correct her rough ride?
