A swollen leg in a horse that isn't exhibiting lameness can be concerning, but it's crucial to understand that swelling doesn't automatically equate to lameness. Many factors can cause leg swelling without impacting the horse's gait. This article will explore potential causes, helping you understand what might be affecting your horse and when veterinary intervention is necessary.
What Could Cause Leg Swelling Without Lameness?
Several issues can lead to leg swelling in horses without causing obvious lameness. These range from relatively minor conditions to more serious problems. It's vital to observe your horse carefully and note any other symptoms.
1. Stocking Up (Dependent Edema)
This is a common cause of leg swelling, particularly in horses that have been standing for extended periods, are overweight, or have underlying circulatory issues. Gravity causes fluid to pool in the lower legs. It often resolves with gentle exercise and movement.
2. Cellulitis
This bacterial infection of the skin and subcutaneous tissues can cause significant swelling, heat, and pain. While lameness isn't always present initially, it can develop as the infection progresses. Cellulitis requires veterinary treatment with antibiotics.
3. Insect Bites and Allergic Reactions
Insect bites, particularly from flies or other biting insects, can cause localized swelling and inflammation. Allergic reactions to these bites can also lead to more extensive swelling.
4. Trauma
Minor trauma, such as a bruise or contusion, can cause swelling without necessarily causing lameness. However, more serious injuries like a ligament sprain or fracture can eventually manifest as lameness.
5. Lymphedema
This condition involves the lymphatic system's inability to drain fluid properly, resulting in swelling. It can be caused by various factors, including injury or infection.
6. Heart or Kidney Disease
In some cases, leg swelling can be a symptom of underlying systemic diseases like heart or kidney failure. These conditions often present with other symptoms such as lethargy, weight loss, or changes in urination.
When Should I Call the Vet?
While some causes of leg swelling are relatively benign, others require immediate veterinary attention. Contact your veterinarian immediately if you notice:
- Increased heat in the affected leg: This is a strong indicator of infection.
- Significant pain or discomfort: Your horse may be reluctant to bear weight on the leg, indicating a more serious problem even if it wasn't initially lame.
- Rapidly worsening swelling: A sudden increase in swelling suggests a potentially serious underlying issue.
- Other symptoms: Lethargy, changes in appetite, fever, or changes in urination are all signs that warrant veterinary attention.
How Can I Help My Horse?
If the swelling seems mild and your horse is otherwise healthy and comfortable, you can take some supportive measures:
- Gentle exercise: Encourage movement to help improve circulation and reduce fluid retention. Avoid strenuous activity.
- Bandaging (with vet approval): In some cases, bandaging can help to reduce swelling, but only do so under veterinary guidance, as improper bandaging can cause harm.

Q: Can a horse be swollen but not lame?
A: Yes, absolutely. Many conditions can cause swelling without causing obvious lameness, ranging from simple stocking up to more serious conditions. This is why it's critical to observe your horse carefully and consult a veterinarian if you're concerned.
Q: What are the signs of a serious problem in a horse's leg?
A: Signs of serious problems include increased heat, significant pain, rapidly worsening swelling, and the presence of other symptoms like lethargy, fever, changes in appetite, or urination.
Q: What should I do if my horse's leg is swollen?
A: Observe your horse closely. If the swelling is mild and your horse is comfortable, gentle exercise may help. However, if you notice any signs of infection, pain, or rapid worsening, contact your veterinarian immediately. Never attempt self-treatment.
Q: How do I prevent leg swelling in my horse?
A: Maintaining a healthy weight for your horse, providing adequate rest, ensuring good circulation, and protecting them from insect bites can all help reduce the risk of leg swelling. Regular veterinary check-ups are also essential.
