Why does a dog urinate randomly during menstruation?

This is because the dog is in estrus and urinates in order to leave a smell and attract the attention of the opposite sex. This is a normal phenomenon. The owner does not need to worry too much. Clean the urine and disinfect it with disinfectant.

If the urine or urination is abnormal, it is likely to be caused by a urinary system disease. At this time, the owner needs to take the dog to the hospital for examination to determine the specific cause of the dog's urination, and then treat the symptoms and causes.
