わんわんわんわんN_1!!

"わんわんわんわんN_1!!" is the OP 1 for the 2013 television anime Inu to Hasami wa Tsukaiyou (Dog & Scissors / 犬とハサミは使いよう), animated by Gonzo. Inu Musume Club performs the song, with lyrics by 畑亜貴 and music composed and arranged by 松田彬人. It first appeared in Japan on 31 July 2013 as the title track of a FlyingDog CD single.

The song moves in a brisk J-Pop mode, driven by bright group vocals, a quick rhythmic push, and a chorus that opens out almost at once. Its compact hooks and chant-like title phrase give the opening a playful, slightly unruly edge, while the ensemble delivery keeps the track lively rather than sugary.

That restless energy fits a series built on absurd comedy and sharp friction, where a book-loving boy wakes up as a dachshund and ends up tied to the dangerous wit of Natsuno Kirihime. The single also included "レモネイドスキャンダル" and instrumental versions of both songs, and the opening later appeared on the soundtrack album 犬とハサミは使いよう オリジナルサウンドトラック 歌と劇伴は使いよう.
