This is an image of my Granddaughter age about eight and my old dog 'Nero' he is and Old English Mastiff. He weighed in at about 17 Stone = 107Kgs and stands about three feet tall to the shoulder = .91m.
He was a lovely soft dog but when out with my Granddaughter he was very protective to her. If she was standing outside a shop with him and someone walked up to her and spoke to her he would pull himself up to his full height and growl. This growl sounded like it came from the Bowels of Hell, I have never heard a growl like it in my life. You could feel the vibrations reverberating on your chest. Needles to say no one came within three feet of her. It was nice to know that you could have left her in the middle of a town with him and she would have been quite safe.
