There is no way to determine this. It has a lot to do with the dog's personality and the owner's teachings. Normally, French Dou can hold back urine after the owner regulates it. If your French bulldog always urinates everywhere at home, the owner can take the dog out more often and let the dog urinate outside, or lock the dog in a small cage and control the time to come out once, and slowly extend it until there is no urine in the cage. The owner inside will give rewards.
