Shown is an eight-year-old pony gelding with weight loss (approximately 45kg), inappetence and non-painful pitting oedema of the ventral abdomen. The heart sounds normal, the heart rate is 40bpm and the jugular veins are not distended. The pony is azotaemic (creatinine 194.5␣mol/l; 2.2mg/dl) and the urinalysis reveals specific gravity of 1.014 and proteinuria (urine protein:creatinine ratio 3:1). The PCV of the pony is 35% and the plasma protein is 45g/l.
