Bull Mastiff is what I think you're talking about.

My two backyard girls have been a little noiser than usual lately, because of the wildlife in the creek behind my back fence. Everything moves around at night, so they have to announce all of those comings and goings. Good things my neighbors bedrooms are on the front of their houses and there is no one behind us.

I think they did scare off a couple of pranksters earlier this week. Two neighbors, across from and beside me, found a sticky black paint of some sort on their garage doors one morning, but mine is guarded by two noisy dogs. I did go check the driveway from the doorway a couple of times that night, but didn't see anything.
