I can't even imagine what the cost of feeding a dog that big would be. Cost of all vet bills go up too due to the weight of the dog, then you have to buy a large vehicle to tote it around. I love big dogs, but what would bother me most is the mess in the back yard. My 4 are bad enough. When we were down to 3 it wasn't so bad, but now, :shame:
I just looked up an estimate of about 8 -10 cups of food a day for a male Great Dane.
