Pack mentality

[jrsygal37]

I am having a very tough time with this now. Jersey who we have had since 10 weeks is now 17 months and has gotten very territorial/aggressive with my other Yorkies. They used to all get along great and all still do - all but Jersey who seems to have decided she'd rather be an only. I am at my wits end. I do not want to rehome her but feel that she may be better in a home without other pets. She is such a great girl. loves to ride in the car, walk, play and she's very smart and pottty trained. But she's like a 5 lb. Pit Bull whenver the girls even walk by her when she's in her mood. I just don't know what to do. I'm afraid she will hurt or kill one of them. I'm told that she is establishing her alpha and sometimes it comes down to her being better as an only dog.

Im just heartbroken
