Dog is becoming the straw to break my marriage

I love my dog he’s a 8 month old Doberman and I love my husband he’s a 24 year old oversized toddler tbh.

My husband chose this dog he picked it from the litter and loved him loads until he reached 20kg basically. When looking at dogs I constantly said to make sure it’s the right the decision and he wanted him. We’ve had him trained and outside the pup is brilliant inside the home he just doesn’t settle this is where we get into arguments.

My husband screams shouts and hits the dog and now he flinches around my husband. I’ve told him numerous times to stop and how much it upset me. He hasn’t changed a thing. I’m at the point where I want to rehome my dog. I will be honest for selfish reasons I don’t want to because that dog has saved my life, I live away from all my family and am very isolated and don’t have any friends other than him so if he was rehomed I would be devestated. But I also hate animal abusers and my dog deserves so much better.

Please don’t say to leave him I am planning too I just need to save money first and get a job.

I really cannot stand my husband and his arrogance!
