OK. Who wins this battle? Female Bull Terrier or Porcupine?
The answer? Neither but one of them "survives" (Warning Explicit Content, It's safe for work but shocking in nature). I caught this on, of all places, The Naval Safety Center's Photo of the Week.
The Terrier named Inca apparently took exception to a porcupine that sauntered up to the home of her and two other dogs. She bore her stubborn terrier attitude and didn't lay off until the porcupine was dead. Inca paid a hell of a price, though. Reportedly she made it through with only pain meds and anti-biotics, amazing.
Are you a cynical bastard that doesn't believe anything you see on the internet? I submit for your approval (or not) that Snopes researched the story and found it to be true.
