I am not familiar with single coated hair but I hand strip my double coated dogs and if I was to hand strip a section like that, it would grow in with the guard hairs which are thicker and darker and lie flatter against the skin. I think Cavaliers might be double coated so there's a chance your pup could have a double coat too.

If I was to start clippering my pup's coat, the hair would most likely revert to the soft fluffy undercoat.
