i think it's super funny when milu howls, so i always run to her to give her attention when she howls. my fiance hates it and says he can't believe i would encourage her to do that. other than wanting attention, milu is a pretty quiet dog. the only time she barks is if you ask her to ("talk" command) or if she is really excited and want to play.
(or when she thinks you are unfair, and she talks back. lol. )
