Over the last few weeks, Leo has gotten so much more obvious and consistent about signaling that he needs to go potty. He used to be SUPER subtle, to the point that I would just take him out randomly because I didn't trust him to tell me (even though he hadnt had an accident in forever).
Lately, he has gotten sooo good at signaling. If I am in the living room, he will go to sit right by the door. If I am not in the living room with him, he will ring the bell repeatedly while sitting by the door. Makes my life a lot easier, because I can relax more about taking him out. Looks like he is definitely completely potty trained now
(he probably was before, but still)
