Thank you all for the advice. I think animals know when you give them a second chance
I tried to read a couple of books on Yorkies and knew about the trachea collapsing, but I appreciate that you're looking out for my little one too. Today is much better with leaving him alone. I've been working on it all day, trying not to greet him until he's calmed down and left for 5 mins at a time, like what the post from Cesar said. He still barked a bit but he's calming down and not waiting at the door anymore.
Also to prove my bf loves him as well.
