Thank you for the post, it was a great article to read. I definitely need to step things up with Cash (yorkie) since I am looking after my sister's labrador as well and I treat them completely differently.
But Mauzer (labrador) is almost ten years old and he is an outside dog - I am allergic to him and can't have him in the house at all times.
I think when we move into the new house (moving again

), I will change some routines to establish Cash as my subordinate.
He is very cheeky with other dogs and with Mauzer and this makes him very hard to take for walks. He pulls and barks and lunges at the other dogs. I usually pick him up then, but since I read the article, I will definitely make some changes. The article is completely right - I would never allow that from Mauzer (or any big dog).
