Protein-losing nephropathy in dogs causes progressive kidney dysfunction and hypoalbuminemia requiring specific dietary modification, blood pressure control, and thromboembolism prevention.
PLN causes complex and progressive welfare compromise through multiple mechanisms including edema causing discomfort, hypertension damaging other organs, thromboembolism causing acute emergencies, and progressive kidney failure. Dietary management must balance protein restriction to reduce glomerular pressure while maintaining adequate nutrition. Monitoring for thromboembolism requires owner vigilance and emergency response planning. Welfare-focused discussions about quality of life maintenance and endpoint planning should be ongoing throughout disease management.
