This happened to me once when Bella was a little puppy. I was walking out the front door and she darted out. She immediately started running in big circles on the front lawn and I knew I would never catch her. Just before my panic went over the top I got an idea. When we are in the back yard and I want to go in, I say "Bella it's time to go in" and she usually follows me inside. I stood on my front lawn and said the same thing and, as I stood there thinking "yeah right, she'll never fall for this," she walked right back in the house!! That was truly a miracle! Fortunately now she doesn't even think about running out front. I think she realizes that trips out the front door have the possibility of her winding up at the vet's or groomer's! LOL!
