Sounds like open fontanel (open soft spot) to me too. I agree about taking your pup to the vet so that they can examine him.
I had a puppy with an open fontanel and it had a bad conclusion. (I don't want to scare you at all. But just wanted you to know that I had first hand experience with it.) How is his hearing and hearing and smelling, etc.?
My first vet didn't notice the large open fontanel on my puppy (even though we knew he was at least mostly if not completely deaf)...I have since changed vets. This is something that should be noticed by a vet at a puppy visit.
Keep us posted and best luck to you.
