Most shops are dog friendly now. I like dogs and see no issue with it.
There was a shop incident in Sweden: a dog was in a shop and was following me around. Now I loved that dog and wanted to stroke him but my sister wouldn't let me. But then I accidentally stepped back and onto the dog's paw: I felt terrible. I had hurt the dog and felt upset for him. The owner asked why her dog had yelped. My sister told her and the dog was put back upstairs.
