She sounded very resentful toward the dog in that she said 'this dog is not going to run my life' and other comments that infer that she has no real emotional attachment to the Yorkie and probably not to her other dogs either.
The kindest thing to do would be put the Yorkie in a Yorke rescue but she seemed quite convinced that she knew all about dogs and could do this. I'm sure she can get some level of success according to her way of seeing things by intimidation and harsh measures. The little dog will be destroyed but she will get her way.
It is hard to see such insensitivity in dealing with a dog that has lost it's home. So harsh!
