1. Your dog doesn't know that bitch won't come back. When the bitch was away, she consolidated her position.

Your dog has been eating too cold recently, resulting in frequent urination. Just observe it quietly for a few days.

If you don't give it calcium supplement, it has nothing to do with frequent urination.

To be on the safe side, see if there is pus at the top of the penis. If you have any suggestions, go to the hospital to check uremia.

If there is no suppuration, there is no need to go to the hospital to spend money. Dogs pee for many reasons, not just because they are in a hurry.
