im not so much worried about the fact she didnt like another dog as i am of her being so young and sounding so mean.... she will play with my cat and they are fine they get a little to aggressive but my cat usually knows his limits as to when he really hurts Luna.. and another time she was whining for no reason and i read somewere to lightly wrap your hand around there mouth and say no, so thats wat i did and she did her vicious growl towards me now that only happened the one time but it worried my husband because he loves her and doesnt want her to be growling at us
