I don't think that's not a stock badge. It would have been added by a prior owner. I don't think your car was "new stock".
(and I'm suspicious about the use of a google photos link, which would potentially let you discover the google accounts of people who view the photo, so I removed it)
This is a new, 2021 Leaf? Any chance Nissan has some kind of pet-friendly upholstery in it? Could this be some kind of add on?
Anything to do with "dog mode" that can remotely turn on the car's fan?
