I have a Houdini too. She never tries it when I am coming IN through a gate, but if I go out, she is between my feet and away in seconds.
And over the years we have had to chain link fence the entire vegetable garden or generations of puppies would have (and have at times) ravaged the vegetables. Photos of a litter of pups chewing Brussels Sprouts off the stem of the plant tell the story . . . But over the years I've learned that loosely stringing the chain link keeps them in. Tight and they shin up it, loose and it wobbles and they have less confidence. Really slack 5 foot fence and they won't trust themselves to climb it. Personally I wouldn't dream of electric fencing around dogs.
