I have a horse that carries his tail to the side when he travels in a circle to the left, but when he travels in a circle to the right he carries it normal. When working the patterns he tries to hollow out his back, put his nose in the air, and sling his butt when he turns to the left but when he turn to the right he can keep his head lower, rounds his back a little better and gets under himself better. What do you think would be causing this?
This could be indicative of a high, hind end lameness situation. Watching your horse and how he carrys/sets his tail can be a good diagnostic tool, and was for me on the racetrack. Sometimes the most subtle changes can indicate something might be wrong and your horse is altering his/her weight to compensate. You are very in tune with your horse. It is most important to have your veterinarian do a complete physical exam and share with him these abnormal characteristics. Thanks and good luck.
