There are usually several reasons for blood in dog urine. It may be food poisoning. Dog food is usually mainly dog ​​food. If you eat chocolate, onions and other foods, it may cause poisoning and hemolytic hematuria. In this case, it may also be in estrus. During the estrus period, the female dog's genitals will have secretions and the male dog's genitals will be damaged. This blood will be mixed in the urine, causing the symptoms of pseudohematuria.

Of course, urinary system diseases, such as cystitis, bladder stones, and urethra, cannot be ruled out. Stones, etc., can cause damage to the dog's urethral wall and lead to blood in urine; therefore, owners must first find the cause and then treat it according to the actual situation. If you can't handle it at home, it's best to go to a pet hospital.
