Deceptive-Pony or Auto-Pony, they never learn since hours of training and searching forces them to make train their bladders to hold excessive urine. Stallions can easily pull this off but mares, it's really difficult, even the ones who don't seem to be the type to act like it. This red poneh, Shatter thinks she's so tough and acts like she doesn't need a break, especially when searching for the supposed, criminal, but behind their backs, even her partners, she grabs herself to calm her urge down and kind of distracts herself from it.
