AITA for telling my girlfriend she is being selfish about her dog?

I am 24 my girlfriend is 26. She has a small poodle who she loves. I have met the dog several times before but have never been around him for extended periods of time. <br><br>&#x200B;<br><br>My girlfriends housemate recently tested positive for Covid so my gf and her dog are staying at my apartment until he is negative and can leave his room. I have not had any issues with the dog so far. My girlfriend and her dog are very well behaved and clean. My only issue is that she wants to keep the dog in my room at night. She wants him on the bed with us but worst case just in the same room as us. <br><br>&#x200B;<br><br>I do not want her dog in my room at night. I told her before she came that I don't want the dog in my bed. I spend 8 hours a day 5 days a week in that bed with her dog. I want alone time with my girlfriend. I told her that she is being selfish and asking me to share the only time I have alone with her a day with her dog. <br><br>&#x200B;<br><br>She said I was being selfish and rude. I told her to stop being so offensive and I will share but she just got angry and called me an AH. am I? or am I just misunderstanding the situation?
