I had a dog named Bandit that would get a running start from one side of the yard were the neighbor had a wooden privacy fence, to the chainlink fence on the over side. He would be going so fast that he could run under the fence. No shit.

He found out he could do it one day when I was throwing the ball for him. It was the craziest thing I had seen. After that day he did it whenever he wanted out bad enough.

Bandit was an oversized English Springer Spaniel. FYI
