What does dark urine in horses mean?

Dark urine in horses can indicate a variety of causes. One possible explanation is an increased concentration of waste products in the urine, which could indicate dehydration. Blood in the urine due to bladder or kidney problems is another possibility. Changes in the color of the urine should be closely monitored, as they could indicate potential health problems. If dark urine persists, it is advisable to consult a veterinarian for an accurate diagnosis and appropriate measures.
