It's part of a ridge on the skull, and is called the occipital protuberance.
This ridge is where the large muscles of the lower jaw attach, and all dogs have it to one degree or another; bloodhounds having a particularly noticeable protuberance!
In dogs with large, blocky heads like Mastiffs or Rottweilers, this can be difficult to notice due to their large jaw muscle attachments.
