Molly

Question
Hi, I have a 3 year old Jack rustle and Beagle mix named Molly. She is
a very dominate dog and can be quite aggressive toward my sisters and
myself. Me being 15 can handle her pretty well but my younger sisters
can not and when she snaps  at them they either 1. Yell and scream or 2.
they let her dominate over them. This is a real problem because she
only snaps when she is on a bed or they try to pick her up. She only
growls at me when I take her from the Bed. Also, she has some territory
issues! any person that walks by my house is going to get chased. Thank
goodness Molly  does not bite them or even snap at them and once they are
 away from the house she returns inside. Mean while she is harassing
the neighbors i am standing at the door yelling for her and she
continues to bark and chase the people.   She has always done this and she
ignores myself and my sisters but listens to my mother but more so my
father.  I am not sure why because i do the same as them. Oh and she steals
food from my sisters! I love molly but she is setting a bad example for
my new puppy basset hound! This needs to stop! can you help?

Answer
Your situation is complex because there are so many people involved and your JRT has gotten the upper hand.  You need to discuss with your parents that a behaviorist is required and in order to obtain one they need to find someone with real credentials, not a dog trainer!, who can teach your entire family how to put your JRT back in her "place" in your "pack" and educate your family on how to appropriately interact with her.  The situation is far too complex to address in this venue.
