I was so worried about getting another yorkie because Bandit is dominantish, but the puppy turned out to be the dominant one in their relationship. She always wins the toy they tug-of-war for, she barks at him if he eats before her (even though her food is out for her), but ANYWHERE else she is SO submissive. She spends the entire time at the dog park on her back lol. It was a very interesting dynamic between them, but it worked itself out
