Screaming or howling

I was visiting my mother at her house. I noticed several large crates and boxes sitting around filled with fruit. I asked about them and discovered that my little brother was selling them. I briefly considered buying some plums, but then I noticed one of the boxes had a dog in it. It was an English bulldog who was rather large for her breed, about the size of a labrador. I bought her instead. I named her <PERSON> and started walking home (which is impossible IRL) carrying the box with <PERSON> in it. Outside, the weather was terrible. It was overcast and terribly windy. As I rounded a corner onto the street I lived on, I was walking into the wind. Holding the box, I could not walk, so I set the box down on the edge of the street and continued to walk, intending to get my car and come back to get her. (Note: I would never do something like this IRL) A couple guys I know from work (we will call them S and H) were walking behind me and called me to get my attention. As I turned to see them, I saw a car rounding the corner. The drove wide and I saw them heading for the box. I screamed "Do not run ove my dog!" but the car's tires went over the box anyway. The box tumbled in one direction and <PERSON> in another. I ran over to make sure she was okay, and it turned out her paw was the only thing that was hurt. H offered to give us a ride to the vet, then I woke up.
