I Live In Colorado

I've never understood the deal with people here bringing dogs that are not service dogs into a store with them such as in Wal-mart, Target, the Aurora Mall, etc. It doesn't bother me, but it's still weird. Growing up in Colorado, I remember seeing maybe one or two people carry around a small puppy while in a store, but things have changed. I guess as long as the dog is small sized then it's okay.
