Following the guideline of feeding a 1/2 oz of food per pound that your dog weighs, your "dog" is about 1,760 lbs. That's about as much as my x-racehorse. For further reference, that's 7x heavier than an average male black bear and over 3x heavier than an exceptionally large lion. It would easily rank as the world's largest land carnivore if it is one. Please return that animal to the zoo.
