The song, written by Gomez and Marshmello along Ali Tamposi, Louis Bell, Brian Lee, Carl Rosen and the song's producers Marshmello and Andrew Watt has been described as a "sticky electronic snack" and "propulsive EDM" which is equally "acoustic-laced EDM and long, lost 80's pop". "Wolves" opens "dark and gloomy" with Gomez singing over a clean electric guitar as Kat Bein from Billboard commented, the build of the bridge is "almost country-pop, but the choral hook is all Marshmello sweetness." In an interview with Zane Lowe for Beats 1, Gomez stated that the lyrics deeply reflects what she was feeling the period she recorded the track.
On November 2, 2017, Gomez released the vertical video for the single exclusively through Spotify. It was later released via her official Vevo account. The video is a FaceTime between Gomez and Marshmello.
On November 17, the official video premiered on iTunes and Apple Music. The video features Gomez wearing different outfits in various parts of an indoor swimming pool facility. Near the end of the video, Gomez walks on the water of the swimming pool. The video was released on Vevo and YouTube a day later on both Gomez and Marshmello's account. Review Found On Wikipedia.
