I have a 7 year old Quarter Horse that is a companion horse due to a shoulder injury she is unable to be ridden. She is very demanding and impatient. She is the top of the pecking order. I have tried numerous times to correct her impatient behavior, mainly because she causes herself to become sore due to constant pawing while I'm getting her food together & as I am bringin it to the fence, I try yelling different things to get her to stop but she just continues. Now about the demanding part, she is super jealous of the other horses receiving attention, I was riding my new horse for the first time yesterday & she was throwing a temper tantrum, bucking & running along the fence line, she also does this if I am a little later than usual getting her feed together. Any advice is appreciated.
