My dad yells at me what do i do?

I was sitting on the couch watching t.v and eatin ice cream and my dad walks in and takes my dog outside to do his bussiness and when he just walks in my dog heads straight for the ice cream carton and so i run up to the coffee table and i slip on my dogs toy and i fall on my arm my head inches away from hitting it on the fireplace and hes yelling at me when i hurt myself and he abuses my family with words like he will call my mom a sacndivian b*tch when he gets drunk he threatnens to hit both me and my brother and he has hit us before and he sent me to my room and compared me to a n***** and he noticed the ice cream when he first walked in before he took my dog outside
