What is going on when a dog has bloody urine?

The common causes of bloody urine in dogs can be divided into two main categories: urinary system diseases, such as kidney inflammation and urethral stones, and non-urinary system diseases, including dietary indiscretion and estrus. After a dog has bloody urine, attention should be paid to cleanliness and diet control, with dog food as the main food source.

Firstly, bloody urine in dogs may be caused by urinary system diseases. Kidney inflammation is related to infection and poisoning, and often occurs as a complication of infectious diseases such as canine infectious hepatitis virus, hemolytic streptococcus, and toxoplasmosis. The clinical manifestations usually include lethargy, loss of appetite, and bloody urine. The treatment principles mainly include eliminating the cause, inhibiting immune reactions, reducing inflammation and promoting urination, and symptomatic treatment. Ureteral stones mainly form when inorganic salts in urine precipitate, causing inflammation, bleeding, and urinary tract obstruction. The clinical features are urinary disorders, renal colic, and bloody urine. The main treatment principles are to improve nursing, remove stones in a timely manner, and control infection. Dogs should be supervised to drink plenty of water in daily life to reduce precipitation and prevent crystal precipitation in urine.

Secondly, bloody urine in dogs caused by non-urinary system diseases includes two aspects: on one hand, it is caused by dietary indiscretion, such as dogs accidentally eating chocolate, onions, and grapes, which can lead to bloody urine. Overconsumption can even cause dog poisoning and death. On the other hand, it may be caused by estrus, which usually begins around 6 months of age. Female dogs usually have a small amount of bleeding, which mixes with urine, causing a false appearance of bloody urine.
