I found the original listing from One Tail at a Time on Petfinder.com for Riley (then known as Laney) and this is what part of it said:
Though Laney is an extraordinary snuggler (and kisser!) who enjoys being held, she seems to be the most independent of her siblings. During car rides, Laney loves looking out the window and taking it all in. Often confused with a stuffed-animal, Laney's cuteness is hard to rival.
Riley does indeed love her stuffed animals, some of which she destuffs! So is she a pup or is she a stuffie? I'm sure she wouldn't care what she was called as long as there was attention and loving to be had!
