A pet store mascot dog (big blackie) falls in love with one of the unsold puppies (white, smol fluff boy) in his owner's shop. They fucked and were very cute. This is downright bestiality btw. (Like they're just normal dogs but we see them as half-human half-dog lol)
This one is cute, though I don’t really understand it but it was a cute read so read it if you want something that has only one chapter and has animals in it ( mostly dogs ).
