A 44-year-old man has been charged with a string of offences after allegedly trying to stab police dog Rumble in East Fremantle early this morning.
Police were called to Hubble Street about 3.20am after receiving reports that a man was attempting to break into a vehicle.
Officers allege the man was armed with a knife when he was advised he was under arrest.
He allegedly threatened to stab Rumble and his handler, running towards the dog team and kicking them.
"Rumble grabbed the man's ankle, causing him to fall to the ground," police said.
"Rumble did not break the skin of the man's ankle.
"The man (allegedly) lunged again at Rumble with a knife, striking him to the neck area (and) then lunged at the officer, striking him to the arm that was holding Rumble's collar."
The man was arrested after more police officers were called to the scene.
Neither Rumble nor the officer was injured.
A Willagee man has been charged with criminal damage, making threats to kill, assaulting a public officer and going armed in public to cause fear.
He is due to appear in Fremantle Magistrate's Court on September 2.
