So my husband got a new puppy

He’s only 8 weeks old and he’s a staffordshire terrier. My mother in law was completely against it and she seems to be throwing a fit that my husband got him. She said she loves dogs, they had several in the past but not right now. She actually adopted a dog for my husband 10 years ago and ended up taking care of him because he was never home, always at sports or friends. So she was afraid she would end up taking care of him. I told my husband to prove her wrong, it was 10 years ago if he can do it then get him. So my husband got the puppy and it’s definitely not how I thought having a puppy would be.. since my mother in law didn’t want a dog I didn’t want him pooping and peeing all over the house (we rent and share with my in laws). I hang out in the garage by myself most of the day as my husband works full time and I only work part time. I am exhausted by the end of the day. I wake up in the middle of the night to walk the puppy so he doesn’t bark and pee in his cage. Most times he barks when I bring him back to his cage so I bring him back out and hang out. I never woke my husband up when we had our son 3 years ago because he worked and I didn’t. I don’t wake my husband up to do walk him in the middle of the night because i feel bad, he works 10 hour days but I would appreciate it if he did since I work part time and watch the dog during the day. I didn’t think I had to wake up in the middle of the night to walk the pup. I thought my husband would be helping a lot more. He comes home and goes to the room (we don’t want the pup in our room since it’s carpeted and we’re renting). I work at a pharmacy and I also work from home, so it’s hard to work from home. I can’t hang out on the couch with the puppy biting it. My mother in law doesn’t help and my husband doesn’t help. I don’t know what to do. My husband said he would much rather a dog than another kid, but I can definitely disagree. I can get some stuff done with another kid. Our first child is in school. An infant wears a diaper and doesn’t bark only cries when it needs something. I can sit on the couch and do work while the baby sleeps. I wanted another baby so bad and we’ve been trying, but our family booked a cruise for June 2020 and we decided we’re going to try again after. Also, my husband complains we don’t have enough sex and thought it would be more often since we got married . Not sure how he expects us to when I’m exhausted basically working 2 jobs, watching our son after school and the dog while I’m not at work. Idk what to do about the puppy :( or my husband lol.
