My favourite may involve you getting a cup of coffee first as it's not particularly short.
I used to have a Rottwieller who was not only my dog but my best friend. We lived on the ground floor and my flat had huge floor to ceiling windows.
I'd usually open the shutters, open one window and let my dog out for her morning amble while I made breakfast. Then she'd just hop through the open window when she was done.
One day however, I answered the front door and let her out that way. It wasn't particularly warm either and I didn't open the window.
She didn't know that.
When she'd finished her 'doings' she did what she normally did, which nearly had me hanging by my finger nails from the ceiling as 20 square feet of plate glass hit the lounge floor.
I rushed in to see her sitting there smiling at me. Not a mark on her, the Dollop!
I stepped outside, scratching my head and wondering what to do when I bloke up a ladder next door called to his mate.
"'Ere," he said. "D'you see that?"
"What?" asked his friend.
"Bloke's dog's just jumped clean through that window."
"Wow!" said his friend. "What kind of dog is it?"
"Rottwieller," I said.
"Ah," the man said, nodding sagely.
He sounded as if it was only to be expected; sort of came with the breed. Oddly, she didn't have an inkling that what she'd done was out of the ordinary either.
It took a while to clean up, but thankfully, it wasn't something that was ever repeated, but she was an extraordinary dog...
