My girl is about 6 1/2 months old. She has gotten into the habit of doing everything, but going potty when I take her out to the yard. We have a bell on the door that she rings when she wants to go out and she definitely abuses it. Sometimes it's like 3 times in a half hour, but no pottying. We never established a potty command with her. Is it too late? Would that even help? She just wants to eat rabbit poop, play with sticks, and chase bugs. It's driving me nuts.
