You know, I swear I can let my dogs all out in an unfenced area, and they're fine. The second someone leaves the gate open, they're in the next county! (Actually usually swimming at the park across from my house ) We have a pool company that does the chemicals for our pool, and they had this one guy coming to our house, and he would leave the gate open EVERY week. We had to call and complain about him. But every Friday, whoever was letting the dogs out would forget, and you'd see them running towards the park.
