Some dogs, no matter how big they grow, will always be puppies at heart. What they don't realize, however, is that they can't do the same things and fit in the same places that they did when they were tiny.
Sully, an enormous Saint Bernard, is having trouble getting used to his size. Recently, he snuggled up on top of his owner and accidentally pinned him down. When his owner tried to get up, Sully didn't budge, which meant that he couldn't either. If you ever find yourself cuddling with a large dog like the one in this video, it's important to have an escape route planned.
