Back in the day a customer of mine owned a restaurant in Biloxi. When he closed at night,he put his Mastiff in the
storeroom. If you were stupid enough to try and steal his beer, you'd pay a bad price.
I'd bet so. If anyone need visual evidence, here you go.
Not one of their Mastiffs are under 100lbs and the largest is 180lbs. And the owner makes a good point. They don't bark unless they can't get to you. They just lunge. Just no.
