Lost by a Neck in the Race of Life

The Pug again.  This time look at the shortened neck.  No wild canid has a neck that looks remotely like this.  This is the neck of a hippo, not a dog.

Here's what a natural running dog looks like (click to enlarge). 

Try to count the vertebrae in the neck of the Pug.  Now try to count the number of vertebrae in the neck of the natural dog.

Not only is the neck of the natural dog  long enough to allow the head to move, but the skull is the right shape, and the legs are long enough to propel the dog forward to either capture prey or avoid being eaten by an even larger predator.
