Henry is taking on the role of the pack leader. He has to assert himself now because your yorkie is coming into his sexual maturity. Yes, henry is marking, and he is growling to let his "brother" know what the boundaries are. As long as your yorkie accepts his 2nd in line position, there probably won't be any trouble between them. When you give attention to Henry first you are acknowledging his dominance.
If you follow the Dog Whisperer's philosophy, you need to establish yourself as leader of the pack. Exactly how you do that... well that depends on you and your dogs. Good luck.
