That is definitely a short or "smooth" coat.
Unfortunately, smooth is dominant in all breeds, and no purebred Shelties carry the gene for Smooth (i.e. you don't see smooth and rough Shelties like you see smooth and rough Collies or Border Collies). So your puppy is not a purebred Sheltie. If mom was smooth, then she's a mix of something.
Enjoy your puppy though, he looks like he could be fun!
