Three Haimaru Brothers

The are the three canine companions of Hana Inuzuka. It hasn't yet been specified whether the Grey Triplets are either Dogs, Wolves or Huskies, given their grey colouring.

The three canines were first seen during Orochimaru's invasion of Konoha. Alongside Tsume Inuzuka, Kuromaru, and Hana, they aided in the fight against the invading Sand and Sound shinobi. They also made a appearance alongside Hana in the anime-only filler episode Kiba's Long Day, in Part I.
