Cane Corso...looks like the three headed dog in harry potter! (it's name is escaping me) Fluffy is his name.
5 dog breeds for protection (ans use as a BOV :) I would love to have a Cane Corso, but it's so big, and it is said to be hard to train. Rottweiler is a good pick.
The Cane Corso. A large Italian Molosser (Mastiff-type) breed, for years valued highly in Italy as a companion, guardian and hunter, its name derives from "cane da corso", an old term for catch dogs used in rural activities (for cattle and swine; boar hunting, and bear fighting). Easy to train they are a loyal, quiet, & protective breed. Training must begin early as this is a powerful & imposing breed which is highly suspicious of strangers, & aggression should never be encouraged.
