The picture to the left is our 10 month old male Rottweiler puppy. As you can see the distance from the teeth to the outer jaw is very wide. This means there is a lot of muscle coming down from the top skull. This puppy's head is larger than even the Rottweiler in the bite force video, and he still will grow up to 32 months old or more. Most Rottweiler have small narrow jaws, this is in the genetics of the dog.
