Hate to burst your bubble, but this is just a typical size male Great Dane. Some owners like to exaggerate the size of their Danes - 54" tall, 250#, when they are actually 36" at the shoulder and 160#, which is what he appears to be. The tallest dog typically is an Irish Wolfhound and the biggest dog in terms of weight and bulk is usually a Mastiff. I have 2 male Danes here, a 6 year old who is 35" at the shoulder and 150#, and a 9 month old puppy who probably will finish growing at 36" or so. Right now the puppy's head is at my chest level. Nice pics, though.
