From Eric: Seamus is a Saint Bernard Great Dane mix. Or a Great Saint or Saint Dane or a Great Bernard if you like. He is 36 inches at the shoulder; 220 lbs. He has the height of a standard great dane and the general body shape except for the head where he is definitely more St. Bernard. When the original Mastiff breed was failing you can see why they used these two breeds to revitalize it as he looks as much like a Mastiff (except in color) as he does either of his two parent breeds. He has one of the most low-key, subdued and affectionate personalities of any dog I have ever owned. Anyone with an Irish Wolfhound mix: I would be interested in crossing him.
I have some good pictures of the recliner I lost when he was teething at six months.
