I'm looking for a fic that I read a while back and I can not remember the title nor the author.

Description under the cut, please see tags, subject is not for everyone. Also spoilers.


I believe it starts with Dean lost in the woods separated from Sam and he encounters a pack of dogs. I can't remember the progression but the dogs get dean on all fours and start taking turns with him. Sam shows up at some point and watches and maybe uses Dean too. The story ends with them moving into a cabin in the woods where Dean is under a spell where he can breed pups and Sam finds homes for the pups with hunters.
