Police said the dog, Umos, was brought into the 22-year-old suspect's apartment near La Spezia and ignored most of the animals to face off against the python, which investigators said the man was using to cover the smell of marijuana, ANSA reported Monday.
Investigators said Umos "soon turfed out the snake and we found the man's cannabis as well as equipment to process it."
"He was fearless," police said of the dog.
The suspect was arrested and the animals were taken to nearby shelters and a local zoo.
