The knife was still in Lucy the dog's head when her owner arrived at Beck's Garage for work.
Jeff Beck keeps the Mastiff at his shop with five other dogs. He says someone must have broke into the building and stabbed Lucy.
Beck knows that the people who live behind his work woke up to someone banging on their door.
They believe a man stumbled over from a nearby bar and ended up jumping the fence surrounding Beck's Garage. That same fence holds Beck's six dogs.
"They're not vicious by nature, but this is their territory," said Beck. "They're just protecting their home turf."
The wound is something veterinarians had never seen before.
'She wasn't crying," said the vet. "She was really docile. Like I said, her tail was wagging the whole time."
Beck's wife, Theresa Zaizar, checked on the dog after surgery.
"I just couldn't believe that anybody could do that to a little pup," said Zaizar.
Lucy will recover.
Police say the stabbing suspect could be the same man who they believe caused an altercation at the nearby bar.
Whoever stabbed the dog could face burglary charges and animal cruelty as well.
