Another thing I've done with mine, I use the patio door to get to the garage when we go for rides and the side door of the house when we go for walks (the front door is never used for anything). That way my dogs always head in a certain direction when "escaping" out a particular door. Although a trainer told me not to that (she insisted dogs need to be kept guessing), it has so far worked for me. Even when the two escapes happened, it was in the particular direction for that door.
