Gintama - episode 55 - 09 May, 2007

Katsuo knocks Hachiro out and makes unreasonable demands of Kyoshiro, which Gintoki and the others oppose by acting as hosts. Kyoshiro stubbornly refuses Katsuo's demands, and in response, Katsuo points a dagger at him as a warning, but Gintoki intervenes. Katsuo and his men leave because Katsuo's favorite dog gave birth. Hachiro's mother hears about the birth and follows them. (Source: Crunchyroll)
