Why does my mom love my dog more than me?

My mom loves a dog more than her own daughter! Whats up with that? I can be in the middle of a conversation with her but if the dog walks up its "Oh look how cute u are!!" or "Oh ur such a good boy!!!" That dog is the biggest devil idiot ive evr seen!!! He's bitten me twice! TWICE!!! And wenevr i yell at him for being bad my mom is like "talk sweet to him hes being good" (he's sitting when she says this only cause i told him 2 5 times after he snarled at me and almost nocked me ovr) 1 time i was trying 2 talk 2 my mom about an argument i had w/my friend and i was in tears about it cuz she was my best frend and now we wernt speaking at all. Of course my dog chose that moment to flip over and start batting at the air with his paws. My mom squealed in delite and all of a suden i just didnt matter anymor. when i tried to gain her attention again she just snapped at me "(my name) deal with it by urself ur old enuf to know how to make new frends geez" I cant b mad at her cuz she gets pissed!
