And guess what? It worked.
When a Staffordshire bull terrier started to viciously attack Ann Bendouli's Jack Russell Lexie, she tried yelling, kicking and pulling the Staffy away - but all to no effect.
So the quick-thinking Melbourne resident had another idea.
"I lifted its tail and luckily I hadn't filed my nails," she explained to Australian news channel 7 News. "And I put it up its anal passage."
"I had to do something," she said. "And that's what came to me."
It did the trick - the Staffy immediately yowled and let go of the pup.
