I have had this problem with one of my dogs thinking she is above my 9yr old because my daughter was intimidated by the dog's bouncy behavior and tried to assert her dominance by not allowing my daughter to take things from her, like toys she wasn't supposed to have. As soon as I figured out what was going on I taught my daughter to assert herself, nicely, and with my help they are now good friends and the dog submits to my daughter's superiority in the pack

I completely agree that your boston is just trying to figure out where Chloe in in the pack, who she is on top of and below. Its a play for dominance so you really need to make sure she doesn't believe she is above your human child, it could get worse if it does continue. I think having your child help with training the boston (in whatever capacity possible) will help to show that your boston has to be respectful of all the people, no matter their size, and please make it known by you that her behavior is unacceptable.
