I know the awful feeling of seeing your four legged child running top speed in the opposite direction. When Gracie was a pup she was a major escape artiest. Thankfully she is much better trained now but I still make sure that she goes no where near the door when it is open.
She runs so fast! I have taught her to come when called but I don't know what she would do if she got loose with a squirrel in her sights!
Glad to hear you were able to get your babies back quickly. It just makes your heart skip a beat, doesn't it!
