Wow that is tough. He is very, very young. Usually when they are kept with their mother she teaches them what is acceptable and your pup did not get that education. A firm NO when he is too aggressive and maybe be put in his playpen or crate. Hitting him on his nose and such really just teaches him to be more aggressive. I am assuming he does it have all of his shots yet so you can't take him for walks as yet. Does he like to fetch with a toy to give him some running activity?
I think one of the breeders will come forth and give you more information. Just keep loving him and be gentle with him. He will mature, but Yorkies do abound with energy.
Congrats and WELCOME to YorkieTalk this is a mega location for information.
