Why does my horse’s urine turn red?

In addition to these problems, which are discussed elsewhere in this chapter, several other specific causes of hematuria occur.

Haematuria, pigmenturia and proteinuria in exercising horses The effects of exercise on urinary excretion of red blood cells, pigments (haemoglobin and myoglobin) and protein were studied in 8 mares performing treadmill exercise at speeds eliciting 40, 60 and 95% of the maximal oxygen consumption (VO2max).

What is pyelonephritis in horses?

Pyelonephritis, which is a suppurative bacterial infection of the renal pelvis and parenchyma, was thought to be the cause of severe hematuria for seven horses with unilateral or bilateral renal hemorrhage [50].
