Let the dog in

I was in a small room like a hotel room.  There was one other person with me.  In the hallway I could here two people arguing and fighting.  There was a dog barking also.  I opened the door and there was a lady outside and she asked if her dog could spend the night in my room.  I answered yes but she would have to take care of my cat.  The dog came in the room.  It was a small whit scruffy dog.  The cat left.  It was a all black cat with shiny fur.
