My lab got out through a door left open by a teenage house guest (woops) and she ran down the stairs, into the yard where the chickens are ranging (outside of the fence) then se went up the driveway and out by the street to check out the ditch.
Now, I really don't want her out by the street, but I am sooooo excited that she had NO interest in the chickens.
I never let her anywhere near them without me there to control her. After the issue we had with the other dog a few months ago I am very relieved right now.
