Hm, Is a dog/ mini dragon companion/ Any animal really ...legit :)? i mean it makes sense to have a cat, avian (or bird species, or maybe a snake haha), I'm sorry, i didn't know if there's some unseen rule that goes to this xD

Read up on the Harry Potter wiki for all the questions you might have. Dragons are not allowed, not sure about dogs though.
