I've read some pretty cute fanfic which involved hellhounds. Here are some hellhounds fic that i've read
-There was a gen fic when Sam and Dean adopted a hellhound puppy (hellhound puppy series)
- a few where Sam can control the hellhounds (Leader of the pack by astolat, Master of puppies, Black dog)
-also read where Sam is a thunderbird

I'm looking for fics that involves Sam getting a pet, controlling a animal, transforming into an animal, basically anything to do with pets/mythical animal of sorts that's not the ones listed above. I enjoy wincest but gen is fine.Thanks in advance!

PS: also any fics w/ Sam becoming half animal(paws, ears, tail)?
