Do i have to listen to my MIL?

I mean i have 2 beautiful pitbulls. In side dogs. The are 8 months old. Tonight we are at the ER cause my SO cut his pinky. My SO mother came in. She heard from the doctor he recommend that he should go back work on tuesday so his pinky dont get infected. So she ask us where is our Dogs. My SO said they are at his cousins house. So she said do you guys wanna stay until monday? My SO said No cause I miss my puppies. Then she look at me rolled her eyes & said Puppies? The aint puppies! I said I miss them even more they are my babies (They are like my children Ive had them cause i had bad depression & i had miscarriages. So instead to keep having negative thoughts I got my 2 dogs since they are 2 weeks. Theyve been in the house since then. She told me they are to big (They not even that big they are still small compare to other people dogs) & she said they are to big to be in the house. They gotta get out the house. & told my SO that im irresponsable & that she "hates" dogs. It just pisses me off cause she told me i should listen to her cause shes my MIL. I mean im not disrespectful. I always respect her. But when it comes to my Dogs she complains this & that. Our 2 dogs is the only things that gets me up early, take them walking. Before i had them i was bad. Ever since i had them they keep me going. It help me alot & i tell her that. But it just seems like she does not like it when im happy. Everything imhappy with. She complains bout it. Im bout to lose it.

& no we dont love with her. We love with my parents we are still finding a better home.my house dont complain bout them only when they stink lol

Btw. The dogs does not go by her. Lol she doesnt come in my house at all. So idk why she complains she said its robbing our money. Seriously? Like honestly the reason why my SO always ask for money cause that idiot always buy weed! Not cause the dogs it just pisses me off when she thinks she knows when she doesnt
