Great Dane
In contrast to the massive size of the Great Dane is the short lifespan that this dog lives, around 8 years. The tallest Great Dane was 44 inches tall, but these dogs are usually slim and don’t carry much fat but they can still weigh up to 120 pounds.
Newfoundland
Now this massive ball of fur once served mainly as a fisherman’s helper. It was chosen for this role since they swim well, can dive into water and have the brute strength of a lion… well almost. If you were to ever get yourself one of these 150-pound, 30-inch tall dog “bears”, make sure you get yourself a heavy-duty brush for all that fur.
