I just brought home this dog from the pound 3 days ago. Yes I have been keeping her on the leash when we were walking around the house or yard because I don't want her to tear the stitches from recently undergoing the spay surgery. Not sure if this means that she believes to be my dog but she was chewing on a rawhide underneath my chair when my 1 and half month old son did something to make her bark. Neither my wife or I saw what he did but I instantly grabbed her by the face and pulled her away. About 10 minutes later she laying down by the bed on the floor my son trips over her and she turns barks and does a little snip. Didn't bite at all but made me VERY upset, i put her on the back to show submission. The snip made it seem like she thought she was above my son in the hierarchy of this family. Please give me some advice, I dont know if I should call it quits and take her back or if I should train her to understand she is above no one and how I should go about this. PLEASE HELP ME!
