My horrible roommate (21F) invited her mother, brother, and his girlfriend to stay at our home for Thanksgiving without asking me (23F) and they brought a dog which is in direct violation of our HOA and lease. I have an anxiety disorder and this is severely messing with me.

I have made it explicitly clear to this trash roommate of mine that I do NOT want pets in our home and they are not welcome, even for visits. I love animals, and have had many pets in the past, but where I am living now is not suited for animals.
First, it's a violation of our lease and HOA contract.
Second, I collect house plants. They are my pride and joy. I have many rare and exotic plants that are difficult to take care of and that are highly toxic to dogs. So this dog could get hurt and also they could destroy my plants which I have cared for and loved for many years.
Third, all of the furniture (aside from the roommate's bedroom) is mine. I mean all of it. The chairs, the dining table, the bar stools, the rugs, the coffee table, the couch, the living room chairs, the night stands, the lamps, and even the art on the walls. She didn't bring any of her own furniture when she moved in. This is the first time in my life I have owned nice furniture that isn't used or bought at a flea market. I'm really proud of it and take care of it every day. This dog is hardly trained, under a year old, huge, and has long fur. I'm worried its going to get fur all over my velvet chairs, chew up my curtains, or pee on my carpet, etc.
Fourth, she never asked me! She never asked me if her family could come visit and she never asked me if they could bring a dog. She has zero consideration for me! My sister visited last weekend and I asked my roommate multiple times, three weeks in advance if it was okay. I told my own sister to leave her pets at home, even though I love them, because they are not allowed in my house and I don't make exceptions.
When they came in with the dog, she claimed she had no idea they were bringing it. I call complete and utter bull****. She just thought she could get away with it because she thought I was going out of town today instead of tomorrow. She lies constantly. I immediately confronted her and said that the dog was not allowed to be here per our lease and HOA agreement and she just said sorry and that she would keep it in her room. It is currently running around my living room so obviously she isn't doing that.
I have a severe anxiety disorder, as in a debilitating anxiety disorder. My throat feels like it's closing, my chest feels tight, and I'm having trouble breathing and I can feel a panic attack coming on. I was supposed to go see my boyfriend before leaving for another state tonight but now the thought of leaving my house and not know what these strangers and this dog are doing in my home is making me want to vomit.
My roommate is notoriously filthy and never helps me clean and is basically the human equivalent of a landfill so I just know any damage that is done will be on me to clean up because she refuses to take responsibility for anything.
I don't even know if I want to go home for Thanksgiving anymore because I feel absolutely sick to my stomach not knowing what is going on in my house.
I've said something to her three times and she keeps telling me she is sorry and that it won't happen again, but the dog is going to be here for a whole week.
I want this animal out of my house!!! My landlords are out of town for Thanksgiving and aren't responding to me. What can I do?
TL;DR: My lazy, filthy, childish roommate invited her family and her brother's dog to stay at my pet free condo for Thanksgiving without asking me. How can I get this dog out of my house?
