Avoiding pet friendly hotels next time

I’m staying at AC Hotel by Marriott right now and regret booking here. I’m not sure how well the room that I’m in has been cleaned, but I can definitely tell that a dog has stayed here previously. It’s hard to breathe, my eyes are red and itchy, my face and body are itchy, and I’m here one more night. It’s a nightmare. I wish they had a system where some rooms are designated as pet free rooms. I’m regretting not looking up pet free hotels sooner.
