You are very lucky Gus listened and obeyed, most will dash off to check out their new freedom.

Last year Cody got out of the gated deck twice on the same day, while I was 50 feet away head down planting flowers for 15 minutes. I never saw him get off the deck.
I was finished and came to the deck to take a break, the dog was gone, OMG, he is gone for good is what I was thinking, now I am crying and shaking, quickly I start to head to the back where the woods are thinking that's where he headed because that's where the deer are, I was shouting his name over and over, here he comes behind me OMG, I snatch him up praising him like crazy for coming to me when I called him. I couldn't believe he came to me because he is always trying to get at the deer.
I was puzzled how he got off the gated deck, I blamed myself for not checking the latch was locked.

So what do I do, I give Cody a treat for coming when called then I go to finish planting the rest of my flowers, this time I'm 100 feet from the deck and was there for an hour. Break time, I come to the deck, Cody is gone again, again emotional break down, beating myself for trusting he was safe and leaving him alone again. I am shouting and shouting his name, here he comes from the side of my neighbors house, again I swoop him up praising him, gave another treat for coming when called.

I know that gate was latched how did he get out, so, I leave him on the deck, come in the house and peek out of the window, I see him jump at the latch and pop it open I holler Cody want a treat as I'm heading to the door that is only 4 feet away, I was on the deck before he could think treat or run, in the house he came. So now that he has learned how to pop the gate latch he is never alone on the deck.

I was amazed that he came when called because this dog is a runner, I would never let him off leash never. I was lucky to get him back twice in one day, I know the man upstairs helped with that.
With these terrier's and their hunting instinct and curiosity of the world beyond their domain should never be trusted off leash no matter if they obey all command words in the house, once loose they are focused on exploring and don't hear commands.
