The photograph shows Polly standing hobbled about 10 feet from limbs being cut off the fence with a chain saw. During a recent ice storm, a lot of limbs and small trees found their way to the top of the fence. Polly was used to transport the chain saw and stood hobbled while the limbs were cut away.
Horses need to learn to stand quietly in hobbles. You never know when hobbles might be needed to be used in an emergency situation. Hobbles also teach your horse patience, not to mention how to stand quietly when their feet are caught.
After learning to stand with hobbles, Polly will not have any trouble learning to ground tie. She will be used to standing and waiting until her rider is ready to go. Hobble training has many benefits.
