red rash after my cat went to the neighbours department

In the morning she didn’t had the rash. I went outside 30 min later my mom called me and told me that my cat sneaked outside when I opened the door (btw my cat is a house cat ) she went to the neighbours door and walked inside and she saw a dog and she hid behind the couch she was the for like an half hour because no one was home. Then when I got back home I realised the red rash and I don’t know how she got that, maybe because of the dog?
