His name is Max, so he must be perfect.
Happy to hear he is a good boy and that you are enjoying your puppy.
Size alone does not determine Yorkie vs Silky, although the silky standard is larger. I have a lot of people ask if my boys are Silkies because of their long coats. Many people where I live don't know that Yorkies can grow long coats. They have only seen puppy cuts.
