Repeated Weight Shifting Between Legs
Look at the signal, then look at the whole horse and the situation around it.
NOTICE
The horse repeatedly moves weight from one leg to another instead of settling comfortably.
You may notice frequent changes in which leg carries the most weight, repeated lifting and replacing of a hoof, slight rocking from side to side, or one limb being unloaded again and again.
An occasional change of stance is normal. The useful clue is repetition.
WHAT IT MAY TELL YOU
Repeated weight shifting can happen when a horse is adjusting balance, physically tired, standing on an uncomfortable surface, restless, experiencing discomfort or pain, or trying to reduce pressure on part of the body.
DON'T ASSUME
Repeated weight shifting doesn't automatically mean lameness, laminitis, impatience, or definite pain.
Instead, ask: “Is one area being unloaded repeatedly, and can the horse settle comfortably?”
LOOK AGAIN
Check whether one limb is unloaded more than the others, whether the horse keeps returning to the same stance, and whether there is heat, swelling, tenderness, stiffness, short or uneven movement, hesitation to turn or step forward, or a change on a different surface.
Also notice whether the horse eventually settles.
SAFETY
Frequent weight shifting with obvious lameness, reluctance to bear weight, marked discomfort, or difficulty moving deserves closer attention and may warrant veterinary evaluation.

What research shows
The Equine Discomfort Ethogram describes abnormal weight shifting as frequent shifting of the primary weight-bearing limb or limbs, often becoming more obvious when a horse is trying to settle into standing rest.
What it does not tell us
Every weight shift is not a pain signal. Frequency, repetition, asymmetry, movement, and the rest of the horse determine how meaningful the behavior is.
