The "Featured Pet Transformations" below that are good illustrations of the concept, except the "Happy Shiba" example starts from a not-shiba (long floppy ears) and through the magic of GPT-Image-1 becomes an entirely different dog (pointy triangular ears). That makes it look more like an image generator than a restyling of your actual pet.
I wonder if there's anything you can do with the image transformation to make it keep distinctive features of the source material? "Tuxedo Cat" for another example, it makes up a different white and black cat from the one that was provided. The white patch in the original goes up around one eye while the sticker has a pointy triangle up the middle, and its legs were both white but in the sticker they're black with white paws.
EDIT - giving it another look, the "Banana Buddy" example for Cute Style is also turning a bulldog into a terrier
