Overview
If your horse stocks up in the stable, check for signs that help you tell simple filling from something more concerning. Mild stocking up is often linked to standing still for long periods, but it can also happen with mud, diet, old injuries or reduced movement, so it’s worth looking at the whole picture.
Things To Check
1. Check whether the swelling is in both hind legs or just one leg, and whether it comes down after turnout or exercise.
2. Look closely for heat, pain, pitting, redness, or any broken skin around the lower leg and fetlock.
3. Watch how your horse moves out of the stable. Any stiffness, shortened stride or lameness matters.
4. Check the feet for a strong smell, soreness, stones, bruising or signs the horse is reluctant to bear weight normally.
5. Think about how long the horse has been standing in, whether turnout has been limited, and whether box rest has recently changed.
6. Review feed, water intake and overall routine, especially if your horse has had a change in forage, exercise or stable management.
7. Look for any recent knocks, cuts, or flies and mud that may have irritated the lower legs.
Common Causes
The most common reason is simple fluid pooling from standing still in the stable, especially if your horse has had less turnout or exercise than usual.
It can also be linked to heat, mud, minor skin irritation or a bit of knock or strain that makes the leg look fuller than normal.
Less commonly, stocking up can be part of lameness, infection, foot discomfort or another problem that needs a vet’s assessment.
What To Do
Start by comparing both sides and noting whether the swelling goes down after movement. A short walk, turnout if appropriate, and a return to normal routine may help with simple filling.
Keep the stable clean and dry, and make sure the horse has enough sensible movement each day. If the legs are muddy or dirty, clean them carefully and dry them well before putting the horse away.
Monitor the legs over the next 24 hours and note any change in heat, comfort or movement. If the swelling is new, worsening or only in one leg, take it seriously rather than assuming it is just stocking up.
When To Contact A Vet
Contact your vet promptly if the swelling is one-sided, hot, painful, associated with lameness, or not improving with normal movement. Also speak to your vet if your horse seems unwell, the leg is getting worse, or you’re unsure whether it’s simple stocking up.
