His 44-inch shoulder height makes "Zeus" the world's tallest dog.

Zeus weighs 155 pounds and eats around 12 cups of food a day.
That’s equivalent to one 30-pound bag of food. 

Not (unless the food weighs 2.5 pounds per cup).   Presumably "per week" was left out at the Salon quote source.  Video at The Telegraph.
