Babies and dog

Hi,

I would like to have opinions on what should I do with my baby girl to be, my boyfriend and his dog. i know its long to read but please im desperate.

I never wanted a dog, my boyfriend did and so he got his dog, we tried to teach him how to be a good dog and he kind of great a it he don't bite, he likes to play but he's scared of everyone and very protective when my step-daughter is with us. He bark at people when they play with her and start to run after and fake to attack them. Just to make them afraid a supposed. Imagine when people are gonna come at my home to see my baby, will he become more agressive? When we go out for a walk or to see people he grunts at everyone he sees. He just listen my boyfriend never listen what I say so im getting mad amd stared to yell at him and its the only time he listen because he is scared witch makes me feel bad.

In last July we moved in our new appartement and hopefully, Im in my maternity leave because we can't leave him alone for more than an hour, if we do my neighbors complains about him. So I'm forced to be with him 24h a day, to take care of him when I never wanted a dog. I told my boyfriend he was his responsability, so he had to walk him, teach him but he's not doing any of that. I have to take care of his responsibility because he is tired from work. But that dog clearly hates me. He destroys everything that is mine, never his things just mine, I got my chair for nursing just the day before yesterday and he chewed the pillow, get stuff in my bag to eat it (my tide-to-go wtf?) amd he eated his own poop and let the rest of his dinner on the floor (he jave food in his bowl. I woke up earlier today I saw the mess he did with my stuff.

And my boyfriend makes me feel like a stay at home mom and I like it but he is acting like a teenager I always have to clean his mess, etc. And he won't change, I tried and he broke his promises more than once (alot more).

I can't deal with 3 of them (my boyfriend, his dog and a newborn baby) I will go crazy if so, what would you do if you were at my place?

Imagine im alone taking care of a dog I don't want, cleaning the house with dog poop on the floor, cleaning all the mess my boyfriend did, trying to educate a dog that never listens and with a baby soon at home (in only 3 months) and a toddler.

I don't want that to be my life and I don't know what to do..
