My little girl does the same thing. If she's off the leash she'll take off running. She did this last week and took off running. I couldn't run because she'll just run even after. Good thing she wasn't crossing the street. She got half way around the block before my boyfriend showed up (who she loves). I taught her "go get him" and she ran up to ran. I would die if she got ran over by a car since we were around the corner from one of our main streets. I put her in time out and locked her in her crate...then I felt bad.
