my husband traumatizing my baby

I have a 1 year old son with my husband and I don’t know what to do. My husband has anger issues. He gets angry about stupid shit and slams doors, screams at me, screams at the dog, and kicks the dog too. the dog starts barking when he screams which just makes him scream louder which makes the dog bark louder. Today he was freaking out and started screaming at me and my son was just so scared.. he put his head into my chest for like 20 minutes after. I can’t believe he can scare the shit out of our child and feel nothing about it.. he was blaming it on me. I just feel sick. He makes me feel sick. How can I be with someone who can just traumatize their child like that. If I tell him to stop screaming because he’s scaring the baby he screams louder.. I can’t take it. I grew up in a really abusive traumatizing house and I can’t stand knowing this man is scaring him like that. I feel sick. I don’t want my baby to be traumatized. I’m worried because my son often isn’t very emotional. I mean he cries and smiles and laughs, but when we go places he just kinda looks around kind of stoic like. I read this can be a sign of trauma and I just can’t stop worrying that he’s traumatized.. I’m thinking about moving to my moms with him. I just need to get this off my chest. I’m not okay. I can’t stand my husband. I can’t believe he can do this and not care. I don’t think he even cares
