We had just replaced the battery in the collar Sunday night. We think we just didn't train them as long as they needed to be trained to understand to go back when it beeps and not go through the barrier.

We've disconnected the power to the transmitter so that, in the off chance that she returns, she doesn't get buzzed when she approaches the boundary. We can definitely put power to it in our vehicle or in our home if there is possibly a way to locate her using it.
