howl of a Maru (まるの遠吠え） 

We, dogs, cannot help but howl whenever we hear ambulance sirens and anouncement from some speakers. Hearing our howling, people ask " Are you lonely?" and " Are you calling upon your friends?" etc., but that's not the case. It's what we call conditioned reflex. Once it is started, we cannot stop howling until they are over. The DNA inherited from ancient times ends up reacting without my intention. I wasn't able to howl well when I was little, but recently, I've been praised by everyone that I've become really cool.
僕達、犬は救急車のサイレンとかスピーカーから流れるアナウンスを聞くと、つい遠吠えしたくなっちゃうんだよな。みんなは、僕の遠吠えを聞いて「寂しいの？」とか「仲間を呼んでるの？」とか聞くけどそうじゃないんだ。
条件反射ってやつだね。一度遠吠えしちゃうともう放送が終わるまで止められない。太古の昔から受け継いでいるDNAが僕の意思とは関係なく反応しちゃうんだ。
