Chronic Progressive Lymphedema (CPL) is a debilitating condition primarily affecting draft horses and heavy breeds. It is a progressive disease that results in chronic swelling, thickened skin, and the formation of painful lesions on the lower legs. While there is no known cure, early detection and proper management can significantly improve a horse's comfort and quality of life.
Causes of CPL
CPL is believed to be a genetic disorder that affects the lymphatic system, impairing its ability to drain fluid effectively. This leads to fluid accumulation in the lower limbs, resulting in persistent swelling and skin complications. Contributing factors include:
Genetic predisposition (common in draft breeds such as Shires, Clydesdales, and Belgian Drafts)
Poor lymphatic function leading to fluid retention
Secondary infections due to thickened and compromised skin
Lack of proper leg care and hygiene
Recognising the Symptoms
Early diagnosis can help in managing CPL effectively. Look out for the following signs:
Chronic swelling of the lower legs
Thickened, scaly, or crusty skin
Formation of folds and nodules around the pasterns
Secondary bacterial or fungal infections
Lameness in severe cases
Treatment and Management
While CPL cannot be completely cured, effective management can slow its progression and improve the horse’s comfort. Some essential steps include:
Regular Cleaning and Grooming – Keeping the legs clean and dry helps prevent infections.
Moisturising and Skin Care – Applying soothing and medicated creams can reduce irritation.
Exercise and Movement – Regular movement encourages lymphatic drainage.
Compression Therapy – Wrapping the legs with appropriate bandages can aid in reducing swelling.
Veterinary Support – Routine check-ups and early intervention can prevent complications.
Dietary Support – Ensuring a balanced diet to maintain overall health and immune function.
Preventing CPL
Although CPL is largely hereditary, certain measures can help mitigate its impact:
Breeding Considerations – Avoid breeding horses that have a history of CPL.
Good Hygiene Practices – Regular washing, drying, and applying barrier creams.
Maintaining Healthy Weight – Overweight horses may experience worsened symptoms.
Early Intervention – Addressing symptoms at the earliest signs can prevent severe complications.
Final Thoughts
CPL is a challenging condition that requires lifelong management. However, with proper care, affected horses can continue to lead a comfortable and active life. Regular monitoring, good hygiene, and veterinary collaboration are key to effectively managing this condition and ensuring the horse's well-being.
