I don't have much experience with aggression either, but here are some ideas....
It will probably help to understand what's causing the fighting. It sounds like your yorkie is resource-guarding, in this case, you. I would say this is possibly a bid to be alpha dog, except that you say your yorkie is "sensitive", which I'm guessing means that she is not confident. Are there ways to improve her confidence? That might make her calmer about sharing you.
Also, I would say that you should not be afraid to give your yorkie a correction for bad behavior. As long as you are correcting, not punishing, you won't hurt your dog's feelings. Which makes me wonder, perhaps you are coddling your yorkie and inadvertantly feeding into her insecurity? I wonder because you seem concerned that your yorkie was pouting for an hour, while at the same time saying she is the instigator.
Think about if it was a child. Say your child is bullying other kids, but if you step in to correct her, she bursts into tears. Would you say, "well my child is very sensitive, so I guess I'll have to let her do whatever she wants"? No.
Just a guess. Good luck! |
