Mushroom

Mushroom was a puppy that Sean and Daniel Diaz took in from Bear Station in Life is Strange 2.

Mushroom is an easily excitable and friendly dog. She appears to grow quickly attached to new people, given how she responds positively towards strangers petting her and how rapidly she becomes fond of Daniel after being taken in by him. She doesn't really listen to Sean, possibly because Daniel took her with him and spends time with her.
