We wish you all the luck with the puppy. Sounds like a waiting game right now.
We got our Papillion about 4yrs ago and she was a runner from the get go. Fast, like a blur when the door was open. After chasing here down a couple of time when other people would come over and not think about the front door being open I built a secondary gate in front of the porch. She hasn't gotten out since. It would kill us if something happened to her. Kid's are grown and gone so she gets all the love. Well, she gives some too.
