My dog understands Simlish! So, the other night my dog was barking at the neighbors (her favorite activity) so I went outside to stop her and, without even realizing it at first, I called "Shu shu!" She understood what I meant, stopped barking and came inside immediately. So apparently, Shu Shu is simlish for "stop that and come inside this house."
My dog knows that after I tuck the little kids into bed she gets her dinner and let outside, so she stands in the doorway hopping and dancing while I try to read them their bedtime stories. LOL So hard to get little ones to settle down to sleep with a performing pooch in their room!
