My dog is only misbehaves towards me

I need help! My pug mix, Pinny, is just like a child. She's so sweet and loving to me while others are around, but if it's just her and I, it's like she's a completely different dog.  She gets snappy  and feisty almost as if she demanding my attention (which she gets plenty of). she doesn't try to bite, but she'll diliberitlpy mess with the chair or a shoe or whatever, to get my attention. I'll call her over to sit at my feet (like timeout kinda) In Which she will look up at me and bark!   Like a kid arguing with their parent. Other times, if I try to take the shoe (for example) from her, she'll drop it and run circles. Even when she gets the shoe, she doesn't chew it, just drags it to the middle of the living room, like "nanni nanni boo boo". If I try to nap on the couch, she'll Mess with my purse as if to say "get up!!" she only does this to me and most of the time when we are alone. Does anyone else have this problem??
