Two pet pugs have turned into fierce guard-dogs, chasing off an alleged would-be thief as he tried to break into their owner's house in Sydney's northwest.
The man scaled fences to escape them, but found himself face-to-face with an even scarier predator - a police K9.
Sneaking in while a family slept, the alleged intruder tried to force his way into the Kings Langley home when he was suddenly spooked.
Then, 20 seconds later he was back at it, but not for long, because pet pugs Charlie and Archie raised the alarm.
"It's a bit scary really and I'm really lucky that we've got the dogs, I won't ever tell the dogs to stop barking again," neighbour Keryn Speck said.
Chris and Keryn Speck spotted a stranger in their security vision just after 5am and called police.
A few minutes later, the couple heard screams from next door.
They jumped the fence, fearing their neighbour was under attack.
"We were just fight or flight really, we just thought our friend was getting in trouble," Keryn said.
"We bolted downstairs and then straight over the fence to find the police dog and the police tackling the guy," Chris said.
The only thing this suspected robber got away with was a dog bite.
"The alleged suspect tried to escape, the dog was deployed and the dog took hold of the suspect's hand," Quakers Hill Police Det Insp Gavin Rattenbury said.
Investigators say the accused was heavily affected by drugs.
The 21-year-old spent most of Friday at Riverstone Police Station sobering up.
Police say he's responsible for four break and enters in the area.
He is now facing multiple charges.
