When we first adopted Sierra we took her to my in laws house for a visit, and we were still working on house training. So we made sure to keep an eye on her. Well.... she walked over to the door, and did not let us know she had to go potty, she just squated and peed! The funny thing was that she squated RIGHT over my father-in-laws boot, she peed in side his boot, not even a drop on the floor!!
