Oh no. My thread title states pretty clearly my problem. However I do think I have a solution. I need to drill into the post/peg that the gate hinges slide over and tap it for a small bolt or screw and put a washer that’s large enough to keep him from being able to lift it off. Previously he knew how to open the latch when there wasn’t a lock on it. The gate is 6 feet tall by 3 feet wide. Too smart for his own good... it is kind of funny, but only because I think I can make it so he can’t take off the gate.
