Stewie definitely likes me better than my boyfriend. He follows me around and generally sleeps next to me (or ON me). Maybe this would work for you:
I don't really play "rough" with Stewie like tug-of-war or anythign like that. I'm also a little too lazy to chase him around all the time. When Stewie wants to play like that or be chased, he ignores me and bugs him, because my bf will play that way.
So I guess what I'm suggesting is maybe have Dave do something "special" with her that you don't -- whether it be giving her a certain treat that she can't resist or have him hold her favorite toy and try to coax her into playing while you're not in sight to distract her.
Another thing that woudln't hurt is having Tia sit between you two and maybe hug him or kiss him so she can see that you like him and that if he isnt' hurting you and you're calm, then he won't hurt her and she can be calm. I bet she'll outgrow this eventually.
