so we brought home a new baby yorkie, 9weeks old. And my chi was so funny! She would NOT look at the puppy

She does a lot of whining? What does the whining mean? I kept them separated with a puppy gate cause my yorkie was diagnosed with ear mites!!!

But the yorkie kept sticking her snout through the fence and you could tell she wanted to play. The chi was acted kind of scared ears down and seemed a little nervous/scared. I am so eager to get Attli's ear mites cleared up so they can play

But what does the whining in the chi indicate as she never does this? Any tips to ensure they get along?
