That's an English Mastiff, the largest of the Mastiff breeds. ....and look at the size of that head! .....about four times the size of his owner's dome. Must be over 300 lbs.

I would expect the car to be leaning wildly to the left if that photo is real.

Thanks Mr.   Funny, I was looking at the Bull and English just two nights ago, but when posting earlier, couldn't recall the names of any of the Mastiff varieties.
