2 days ago I took on the training of a new client, whom was a rescued mare. I won't be starting her training until this weekend. She is 13-14 hands tall, supposed to be a Quarter and is between 6 and 8 years of age. Her owner, Heather, messaged me today and said that she noticed her front legs shaking really bad. I have never heard of a horse's front legs shaking so I had to turn to you all. I am not sure what is causing this. This mare loves to run all the time. She is on sweet feed and on 10 acres. She just had her hooves done the day she arrived at her new home as well as deworming, ect. Has anyone heard of this? I'm sure she isn't shaking because of the cool air!
